Slackware for desktop and server needs

Hi everybody. Newbie's here. I'm a bit tired of what I see in ubuntu, fedora, arch, etc. I mean there so much ppls effort in making these distros... overcomplicated. I feel myself sitting on a black box without any clue what could happen next. That's just my two cents about what's going on in gnu/linux world.
It's time for me to have a taste of Slackware. However I'm not sure if it worthy to try. Mostly due to lack of experience with such distros. My usual cases are: desktop (some gaming, some graphics, a lot of office work like browsing and text editing in LO, some tv shows) and server (syncthing relay, openvpn server, maybe nextcloud server in future).
I've just looked at the list of packages in official repository and got a question. From what I can see there are up to 20 programs I've used to use on daily basis that are not a part of official Slackware or alienbob public repository. It's kind of a strange for me that Slackware in 2020 doesn't have a decent video player, office suite, etc. So it's up to me now to bring what I want.
Any advices for a new user? I'll appreciate any advices, especialy about how to manage remote Slackware server (from installation to maintaining). Also I'm interested in making a desktop gaming platform with steam and proton. Cheers
