One EFI + one ROOT partition is what I do on both my laptop and desktop for years, /home is a subvolume to my root partition. This setup suits my needs as I don't have to worry about how big should my root or home (gaming) partition should be.
I use Arch on my desktop and Opensuse on my laptop. They both have options to set up subvolumes from their installer, Debian does not, and I'm not sure about other distros, but you can always set that up after installation, just make your home partition the last one (after the root partition) so you can easily delete it after and grow the root partition without much blocks relocation.
No problem here with Opensuse slowroll (Sway WM) and a Realtek bluetootth radio, I'm using blueman for managing enabling/managing bluetooth connections.
Xrdp with it default configuration on debain12 worked for me pretty fine to access it from windows 7's remote desktop protocol on a local network. There was no sound though, so you may need to tweak it to use pipewire or whatever you are using on your linux machine, if you are using any.
I could be wrong, but i think that was probably on the alpha release, which is now the beta release, so maybe the next stable release will have wayland by default.
Thank you for the links, I will hold on using RAID and stick with BTRFS single until I upgrade my storage to higher capacity or my server to something with more reliable SATA slots
Not everyone is playin triple A titles, for someone like me who prefer old or/and 2.5D games (which are usually under 10Gib), the 64gb variant would be mostly fine.
Mtp is your friend, here is hiw I do it on my devices (samsung a23 and both opensuse and arch):
