Hot water and a squirt of dish detergent cleans most things. Add a bit of bleach for disinfecting if needed, and use vinegar on mirrors and windows.
If you walk round a room and wipe everything, it gives stains a chance to lift and germs a chance to die and there’s no need for scrubbing. I wipe twice then dry. (But for living room, bedroom a dry ish wipe like @Lizzbear described is ample)
Clear floors and flat surfaces = tidy at a quick glance. A bunch of flowers will draw the eye, and is money better spent than most cleaning products. Although a static duster that dirt clings to is a good buy.
Focus on cleaning the kitchen (so people feel comfortable accepting food/drinks), and the bathroom (where you can’t distract them) and then speed tidy wherever they’ll spend most time.
In the long term, cosy homey is achieved by things having a place and being in that place and often a lot of decluttering is necessary. My big breakthrough was realising that if I had a pile of necessary, essentials sitting out in the way, that was a sign to get rid of something taking up cupboard/drawer/shelf space near by so I could give the daily/weekly things a home instead of prioritising cupboard space for storing things I rarely used.
now there’s a place for the laundry in progress, a place for the charity shop donation, a place for the paperwork that’s not quite done, a place for the school bags, etc. it’s definitely not minimalist here but it’s calm.
