Need help with making Linux my home

I'm starting to get ads in my Windows notifications so it's time I move.

I got Manjaro KDE Endeavor OS with KDE installed and got my most played non-steam games running through steam proton which is awesome.

But I have a few big issues.

1. My network randomly drops. A restart fixes but I can't even download Cyberpunk with my 1GB connection before it crashes. Klogs showed something about the network manager successfully shutting down but I can't find much else.

2. No Radeon software. I sometimes need to record clips/ stream so relive is nice but the biggest problem is my second 1080p monitor I Super Resolution to fit more programs on it. I can't find a way to replicate that functionality. I also do not know how to control Radeon anti-lag, chill, Smart Memory Access, etc.

3. HDR controls. Nothing in the display settings so I'm lost

4. Alternative Software I haven't spent a lot of time looking but things like wallpaper engine, rainmeter, powertoys.

If anyone ran into the same things and has solutions it'd make my day.

EDIT: With the overwhelming note from everyone here I distro-hopped to Endeavor OS with KDE (I liked that it let me install multiple DE's) biggest loss is the App store but I was already using winget/choco on Windows so having to do pacman -S is pretty much the same. EDIT: Added KDEs Discover and its backend, seems to be alright.

installing plasma-wayland-session and switching to Wayland let me set display scale below 100% removing the biggest need for Radeon Software.

Network thing I'm still digging into but it persisted from the distro hop and I think is Steam-related because if I don't launch steam it just doesn't happen
