What would be useful to study for office type of work?

Hi, I have 4 children and 1 on the way so work is a while off for me yet but I'd like to get some new skills to help me with a change of career later down the line. I used to work in childcare but I definitely want a change from that and will need something working from home a few days a week or even full time once all the kids are in childcare or school. I'm quite good with computers, constructing emails etc. But definitely need to update my knowledge in these areas.
I wondered about doing an online course or something to learn the ropes on computer software that is commonly used etc.

Has anyone got any tips of the most commonly used software/courses/jobs that I might be able to do from home.... And I'll be mid 40s before I switch to a new job!
No idea where to start or even what sort of job might interest me, but I'll definitely have to work from home for the majority of the week with school holidays and 5 children etc. Something that I could maybe catch up on in evenings and weekends maybe or just part time hours would be ideal but maybe I'm asking too much!

I did a computer course at my local college, and got part time office work on the back of that. If you want to work from home though, you will still need childcare (obviously different during lockdown!) and most office work in my experience will expect you to be physically present in the office, particularly entry level roles where you will likely be dealing with lots of paperwork and other members of staff.

It's tricky, one of my children has extra needs with school so may end up home educating too which at his age isn't too bad as I can set him up and be around for any questions but will need to be at home all week.
I had a look at a few agencies and HR work attracted me but I think it's going to be too complex for what I can commit to. I also saw remote data entry jobs and payroll assistant jobs, and wondered if that might fit in more. Perhaps I could then progress on to something else a few years down the line.
I feel like I need to have a job that I can feel cofident in doing since I've been out of work for a long time and I'll be changing to something new. Quite daunting after taking time out to raise children!
