I mean, every market has 2 or 3 whole aisles dedicated entirely to cleaning products and each seems specific for one thing only. I feel like some soap with a disinfectant is enough, but most people I know do a whole 3 stage cleaning ritual - soap (and rinse), disinfectant (and rinse), bleach (and rinse to finish)
90% of my bathroom cleaning is done with the bleach and vinegar solutions (but DO NOT MIX them!!! Use separate rags, etc.) Toilet bowl cleaner is good for the angled bottle and the bluing is absolutely worthwhile.
Tub & Tile cleaner is good for hard deposits, but doesn’t really get brought out very often.
If there was anything else I’d add, it would be a general purpose light cleaner - despite the name, Windex is ideal for almost everything else.
Also, add something like Mr. Clean into this list and you have everything you need to clean your entire house forever.
EDIT: Something people may not realize about bleach. You really do NOT need a heavy concentration, but you have to leave it in contact for a while. Spray on the diluted solution, leave it while you clean something else, and then wipe it off. But crucially, if you increase the concentration, you don’t significantly reduce the amount of time it needs to work.
