Thank you for the comprehensive reply! I’ll have to look into CLN, I’d like to ideally have it be as optimized as possible. Do you know offhand if you can operate a full Bitcoin node & lightning node on the same 8GB RPi? Not sure if I’ll need a separate board or just another SSD.
Umbrel makes it pretty much that simple, but it's a little harder to grasp what exactly is going on. I started with Umbrel, started over again with cli, and ended up going back to Umbrel with a better understanding of the architecture and tradeoffs.
I found it to be pretty complex when initially just trying to build through cli. You need to pick a lightning implementation and identify which packages will be necessary to complete it, which GUI front ends work and which don't for each implementation, find a peer to bootstrap and get your node visible, find someone who will turn up a channel with you -- for me it was a lot. Worthwhile to learn though, imo.
I opted for Core Lightning (CLN) as it apparently is much more resource-optimized than others, but I'm sure there are other reasons to use the different implementations.
Here's what helped me most for basics and for CLN specifically:

Thanks for the zap! Once the Bitcoin node is fully synced I don't think you'd have as much of a RAM concern. And lightning wouldn't add much to the storage requirement. If you have 1TB you should be good
Any time my friend! 💜⚡️ Awesome, glad to hear that. Bitcoin node has been synced for a while and I should have the storage space. I’ve got CLN installing now, I’ll play around with it and report back 🤟
