raspiblitz node should be fine and enough I think. I used BTCPay server just because I don't enjoy letting the node prevent me from using the rest of the device, given the low system resource use (or rpi5). Solutions like rasppblitz come w/ their own image and since they're not a traditional os, they prevent you from running other stuff on device, using for other things. I've used Amboss Space to trial and error where to open channels to. Tested opening channels to big players list. ACINQ has higher incoming fees, 1ML.com node ALPHA is a node only to confirm node ownership, doesn't route shit, CoinGate has good fees but can't route shit (in my experience). Has been a trial and error experience. Consider your use cases and check where the nodes are connected to and their routing fees tab on Amboss Space. You'd think there would be guides about where to open a channel to, I haven't encountered personally...
