so to summary your first steps were:
i have 2 question - if you want to run rather advanced stuff
all of your described usecases are possible - no exceptions, but after you obviously spent decades of time in other desktops, you might move out of your comfort zone to make the next step. ubuntu is pretty easy for the easy stuff, linux as it is makes a fantastic system if you want to do some advanced stuff, but it lets you do the decisions (which means you(!) have to gain the skill to do the decisions)
we’re here - the community is here to help … but not here to do pre-sales for someone … my tipp:
long story short - i think 90% of users would be happy with windows, mac os and linux just the way all of them come out of the box. most of the time they spend in a browser, checking photos or consume some media … all of before mentioned OSs can do that pretty much without any hickups
if you go into the advanced stuff its a different story. macOS will do lots of decisions for you (but they might not be in your interest). windows has such a big user base that you have a great chance to get some ready to use description because somebody faced the exact same problem years ago. linux - advanced stuff - but no willingnes to learn - yeah man, that won’t be a good match
let me get this right …
the hair, the eyes, the mouth, the arms, the legs … all ok
holding hands, wearing makeup, wearing a bag, wearing shoes … sure no problem
but omg! omg! omg! TITTIES???
