Well, it's very subjective!
The two key things I would suggest you look for are the CAT and the option of external antennas.
The higher the CAT number of the router the faster the speeds it can achieve are. There's a description here but I would personally suggest that while a CAT4 will do the job, the extra money to get a CAT12 will probably be worth it.
External antennas may or may not be needed, but if your router doesn't have the option then.... I would get one that has the option and see how you get on without as you can always add antennas later.
Brands?
Very personal - but I won't go near brands like Huawei with their questionable security history.
I've had good experience with the Netgear Nighthawk M1 which can be picked up second hand for reasonable money. They're really easy to setup and use (as are all the Netgear routers).
I'm currently using a Teltonika, but I think the cost would be greater than you really need to spend for your use case, although they are excellent!
GL.iNet have great reviews consistently - I've never used one but they'd be on the evaluation list for me.
The ZTE MF286D also seems to be popular and is a lot of router for the money. Might even be the one I would recommend.
Test your 4G speed first before you comit to a 5g router - 4g may well be more than adequate
All types. Unless you want DIY, simple kit like Ring, Eufy etc, then you need to look at professional applications. They're not actually that expensive but offer far more robust performance.4G ones?

wouldn't bother with a router at all (unless having internet in your garage would be useful for something else?)
If whatever camera you get comes with a 'default' password then change it.
You'd be surprised how many people don't![]()
