you did nothing wrong. ubuntu is a perfectly fine distro for beginners. the reason i dont use ubuntu anymore is the age of the packages started to bother me. also its kinda annoying that releases hit eol at some point. i like arch for the rolling release (no eol) and the fresher packages.
if ubuntu worka for you, keep using it. there is no correct distro.
normally id say “linux is free, there’s no harm in giving it a go”, but between your lack of free time, nvidia graphics card, dependence on proprietary software, and previous experience (and slight distain) for linux i’d say just go with win 11.
there may be a way to get your music software to work in linux, but youll likely need to mess around with wine configs and it may never actualoy work right.
if you are interested ever, fire up a vm and play around with linux to get comfortable with it. maybe when win11 reaches eol (or even before) you’ll want to make the switch.
none of this is said to scare you away from linux. searching for drivers is rarely a thing in linux. there are built in tools in most distros to deal with graphics drivers, but apart from that, given the open source nature of linux, everything else is just handled by kernel modules and are basically seamless unless you have some weird proprietary hardware. linux is fairly easy to use these days, but there is quite a bit of a learning curve because it is a fundamentally different os than windows, and the way you solve problems is very different.
