I’m running their docker and it works pretty well. Never have to touch it except for updates.

I've been running OC10 for a while now and have hit a few bumps here and there. I didn't realize OCIS is available as a self hosted thing. Since first reading this thread a while ago I've been working on getting it running. Using docker I manage to get it to open to a blank blue page where I'm supposed to be able to log in but the form doesn't show up no matter what browser I use. I may look into it again in the future...
I've had ATT prepaid for me and the other 3 in my family and with all of us it's about $100/month. We don't need unlimited since everyone is almost always connected to wifi. Also they roll over unused data up to 30gb. The wife and I have 25gb plans and the kids have 5gb plans and we can use those for tethering too. Been on it for over 4 years now...
I've had really good luck with my iPad 7th gen and https://songbook-pro.com/. At this point i have about 2000 songs in there and it works perfectly. And I gig with it 2-3 times per week. They do have an Android version but I've never used it. I'm sure it works the same.
If you'd like to stick with transmission, this docker works very well: haugene/transmission-openvpn
