Do you use docker for anything else self hosted? You should give it a try. I literally had not heard of grocy till I read your post but I self host other things with docker. I googled them, visited their github looked at their docker instructions - theirs downloading a docker compose file and lsio’s which gave a run option rather than compose.
I pulled up an ssh to my server from my phone and literally entered the run command from here just modified to have my preferred storage path.
docker run -d \
--name=grocy \
-e PUID=1000 \
-e PGID=1000 \
-e TZ=Etc/UTC \
-p 9283:80 \
-v ~/.config/grocy:/config \
--restart unless-stopped \
lscr.io/linuxserver/grocy:latest```
I then opened my browser to http://ip:9283 and was prompted with a username and password. I googled and found out the default is admin/admin. I now have grocy temporarily running on my server. If I want to run it permanently I'd include it in my existing docker-compose stack or create a new one with just it in it.
I understand it's frustrating and you may not want to use grocy after all and someone might have a good alternative, but getting to terms with docker will make your self hosting life much easier - it took me longer to type this post than it took me to get grocy up and running with docker.
Not OP but fully agree - I don’t enjoy video content so my personal block list would filter youtube.com and any of their shortened aliases like youtu.be and I personally would also filter x.com as if you accidentally click it you’ll likely get the you need an account to view this nonsense
