If you have gained some Linux skills after using Ubuntu for some time, you may try switching to these distributions to explore the world of Linux distributions further.
Ubuntu is one of the best Linux distributions for beginners. It's an excellent platform for people new to Linux. It is easy to install, has tons of free resources available along with a massive list of applications available for it. https://itsfoss.com/distribution-after-ubuntu/

I'll second this. If the goal is to learn Linux, LFS is the way to go.
After that, Gentoo will make sense. As far as non-systemd distros, Slackware is a good choice, and while I haven't used it extensively, Void Linux seems another good choice. Void has a bootable Raspberry Pi [voidlinux.eu] image, and the rpi3 images are aarch64. Boots damned fast, too, and did I mention no systemd? Wound up with Gentoo with distcc on my Pi though.
Pulseaudio has come a long way. I've removed it from my “# lennart” section in my package.mask on Gentoo and now sits as a globally enabled use flag. It adds sensible capabilities like switching audio output sink on the fly while otherwise being pretty much transparent. No perceptible lag either. Big improvement now that Lennart's moved on to fucking up init systems.
