I use Aurora, done by the same guys who make Bazzite (de facto PC gaming distro) Aurora is immutable, a flavor of Fedora, meant as a general purpose workstation. It comes with KDE, but UniversalBlue has some distros with other DE's built in, as your post suggests you don't like KDE
I had tried Manjaro before that, but I kept messing up the network drivers somehow. Thus, I looked for immutable distros that are harder for me to break. If you're not as reckless as me, Manjaro might do you good?
The only thing I'd hesitate on is the integrated graphics. Tbh I have no idea how that will behave. Aurora's system requirements lead me to conclude that if your laptop is later than ~2014, you should be okay.
My Aurora desktop starts using ~2GB memory at boot, so your 16 should be fine.
Before I forget, their GNOME workstation distro: https://projectbluefin.io/ if you're into that.
I recommend Aurora because I already use it, and think it's cool. I've only ever used it on one machine, so if you go that route, I hope your experience is good, too. I like KDE, and Aurora is immutable so it's harder to mess up critical components. Works for me.
