You don't really need to switch to a different distro. Just avoid snaps/flatpack/... and use a more lightweight desktop like XFCE and you should be fine.
I always like to use zorin os lite or xubuntu, both based on xfce. linux mint could also be a good choice, or maybe, if it's still not good lubuntu
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
