Hey, Charlie; welcome!
Power isn't the first question you need to consider, what feels right in your hands, and is well supported by the manufacturer are two really important factors. Many first time router buyers are swayed by (low!) prices and then suffer 'buyers' remorse'.
A lot of us here have Bosch 2 1/4 hp routers and are really pleased with them.
'Cherryville Chuck' swears by his Hitachi routers, there are also many DeWalt owners.
Mine is a Bosch 1617EVSPK...both a fixed base and a plunge base..
It has both 1/4" and 1/2" collets included.
If you are only doing small items you might find a 1/4" trim router perfect for your needs. DeWalt makes a very nice package with both a fixed and a plunge base, as does Bosch.
I'm the wrong guy to answer table questions but there are lots of 3rd party tables that will take pretty much anybody's router.
You want either an Aluminum or cast Iron/steel top...no plastic tops!!
On the indentation question; you mean concave or evenly deep across the span?
