A few more bits from me.
We get the cleaners in once a fortnight, but they do a full house clean in that time (including changing sheets if we leave clean ones on the bed). Mop floors, clean the bathroom, dust everywhere, hoover everywhere....
I keep a few yellow j-cloths (reserved for bathrooms in our house - green or blue are for any other cleaning jobs) in the upstairs bathroom with a bottle of spray cleaner and another of bleach. So once a week, I do a very quick clean of the bathroom (usually after a shower so things are nicely steam damp and easier to clean off), and bleach the loo. And we have a bottle of shower spray which we use after every shower and it helps reduce spots on the screen/tiles. But keeping the cleaner up there means it really is a fast job (and the used cloth goes straight into the laundry hamper for washing).
I don't worry about downstairs so much - DH bleaches that loo weekly as well, but the sink and shower are far less used than upstairs so the once a fortnight is usually ok, and I have cleaning stuff under the sink in the kitchen if I need to do them another time.
We always keep the kitchen clean - cleaning up properly after every meal. And I sweep the floor most days, but don't worry about mopping unless it really needs it (and often, a floorwipe will do a good enough job in between cleaners visits).
I shop online for food frequently, and have built up my "favourites" to make it a quick job. I keep my stores cupboard well stocked with staples, including things I can cobble a meal from if things go haywire and I miss shopping for a few days longer than usual - stir fries using noodles or rice, tinned tuna and sweetcorn with some some seasoning;; or pasta and a jar of decent sauce (and some bacon lardons fried up, or whatever veg is in the fridge). There are always eggs.
And frozen veg and some frozen meat. As well as bulk-cooked dinners and leftovers and easy meals. So some pizza, fish in batter, oven chips, chicken goujons etc.
Bulk cooked dinners I tend to do either on a day I take off or a dedicated weekend day, if I have time to do either. Or else, when I am in the kitchen on Sunday doing a roast, or just organising school/work lunches for the next 2 days, I will have a large pot of a sauce going as well. I'll do a spaghetti bolognaise sauce, but make enough for Monday's dinner (so just reheat sauce and cook pasta when I get in) and to freeze at least 2 more family dinners (and I try to put some in individual portions as well - for nights that there are less people home or we have unexpected extras to add to the pot) - it's really almost no extra bother as you are cooking it anyway, and I get out the electric blender to chop the veg for larger quantities, so I actually get more veg into sauces like that when doing bigger pots (pepper, courgette, carrot, mushroom as well as onions and garlic in a spag bol, say). That same week, I might use a freezer meal like a curry sauce from a previous week's batch cook on another night - just defrost the sauce the night before.
I also try, if I need potatoes or veg, or to marinate meat etc, to do those the night before as well, after dinner when homework is being done and as part of my cleaning kitchen and prepping for tomorrow time. So I can just turn on pots when I get in home. Or have the oven set to turn itself on so it's already hot to cook when I get in (and sometimes I even get the dinner in so it's ready shortly after we get in - casseroles or lasagnas etc). The prep time after dinner also includes making school/work lunches, and getting breakfast stuff organized. Before I go to bed, I lay out the juice glasses, cereal bowls etc so breakfast can be organized easily. And upstairs, I lay out my clothes (DD can do her own now, but I used to do hers, and pack her crèche bag when small), ready for the morning as well.
And making sure everything is in school bags like signed notes, money for X trip, homework journal, housekeys etc. All phones are charging up if needed. And that I've put anything I need in my own bag for work.
There is a diary on the kitchen counter-top to manage who is due to be where (DH and I both travel internationally with work at times, we are both on a few different Committees and I am a Cub Scout leader, and DD has a lot of afterschool activities, matches and events, trips with Scouts or school etc). I use that to help plan what days I need easy, fast meals and what days I can afford to spend more time on cooking a bit more (e.g. making a stir fry or a dinner involving a freshly made sauce). Or the days that I need 3 different dinners at 3 different times (another time when single portions are useful in the freezer - if we're going to eat at different times we can each suit ourselves as to what we eat as well).
Online banking for bills as much as possible, or write cheques on the train etc. Lists for admin jobs. And just keep on juggling - it does get easier!
And try to make time for personal unwinding. The odd bath rather than rushed shower. Listen to an audiobook or useful podcast while walking/running. Make time for a walk over lunch at work (even if that is to go do a shopping chore, take a long route to get some extra steps, and also fresh air and sunlight). And eat well - as much fresh fruit and real veg as possible, and sensible treats and cheats (so we do have oven chips for fast dinners some nights, but they are less bad than deep fried ones, and I try to add as much freshly fried or steamed veg as I can to jars of sauces to mix with meat and pasta).
