Help for searching a new distro

Hi everyone. I have an old ASUS S56C and I use it everyday for web (Firefox) and graphic design (Photoshop with Bottles, Inkscape). I have used for years Lubuntu, and it was all good with LXDE ambient, but with the latest versions it switched to LXQT and with snaps I don't feel it comfortable anymore.

So, I'm looking for another ~_{easy weight}~ lightweight distro, no fancy, only for Firefox, Bottles and Inkscape. I'm opened to any suggestions. Thanks in advance to everyone.

EDIT: Thank you all for your time and answers. I've read them all and I think I will start with Debian with LXDE. Thank you all again.
