Mikrotik SXT LTE6 works for me as I am in a very remote place. RouterOS is really great piece of software, you have web based GUI, you have fully featured CLI with all things you need from router: NAT, firewall, port forward, I cannot name them all, I believe I barely use few % of what is inside.
Ubiquiti UAP-AC as an AP.
I dislike the mikrotik devices because they lock the functionality of the device. I was unable to set up a pair of repeaters as anything else because of this. It was not really advertised and it's totally artificial.
Oh come on, a dongle? In 2021, really? Most dongles on the market are Huawei anyway and they do NAT, no bridge or modem mode. You have to pull down some pin to ground and reflash them to get actual modem functionality. I've got one in my drawer. Plus when they get hot they'll start causing issues.
