Church - Should I plan to upgrade my router (from Ubiquiti USG) or look into a better option

So, slowly but surely. I have been upgrading the church’s network, that I help support. To get them in to this centennial, I currently have an Ubiquiti USG, POE switch for cameras and AP’s. I’m curious what other’s use? Not sure if I need to go more enterprise level router or not. Fortigate, Juniper, Meraki, many others out there that I have been reading on. I like Ubiquiti just for the fact, I don’t have a yearly fee, so that’s a plus. I’m just wondering for security or other features that I may be missing. Or am I over thinking this and move on...
