Ubiquiti’s hardware is limited in some respects whereby with Mikrotik you can implement anything, its just a matter of how and the performance. Ubiquiti for core, especially when deploying CGNAT, is a bad idea.
Is there something similar to Ubiquiti's "unified configuration" thing (where you can configure your whole network in a coherent way, maybe even from some gui)?
I love my Mikrotik homelab setup, but it's held together by carefully crafted per-box configs that are not easy to change all together (e.g. adding another VLAN, etc).
Maybe it's just my newbie status at this, but hopefully there's some cool piece of software that I just don't know about yet!
MikroTik is actually mostly configured via a GUI. It's pretty rare to use CLI except to automate stuff.
However, there is only a limited "Quick Settings" option, which supports most basic configurations. For anything more advanced, you do actually have to set it up yourself.
However, the problem with recommending Ubiquiti in the context of an ISP, is that once you hit a wall with it, you are done. You cannot change things that are not supported to be changed, you cannot make it do something it was not "designed" to do.
On Ubiquiti, you can ssh into the VyOS-derived OS on the EdgeRouter (if talking about EdgeOS), but anything you do there cannot be accessed from the webui anymore, and changing anything in the webui will of course destroy what you changed manually over SSH.
At that point, you have an offbrand Linux router that is hindering you, and you either go with MikroTik or upgrade to Cisco equipment. But that Ubiquiti is going on a shelf.
In general, it's quite different running an ISP and running a homelab.
With MikroTik, you can make ANYTHING and everything. And there is no paywall for additional features like some vendors.
Finally, to underline my point, it is required to learn MikroTik's RouterOS before starting an ISP, if you don't want to end up with problems.
