Fred,
I have used wx-proof fittings designed for small electrical conduit
and/or cables to bring both ext cords, heavy power cable and RG-8
sized coax into outdoor compartments. Found them at local building
and electrical supply. Typically are plastic with rubber stopper and
compression nut for fitting/sealing. Stopper come with a range of
hole sizes for cable.
I use bulkhead coax adapters on a 1/4-inch aluminum plate in a large
rectangular wall opening to the house. I would not do that if doing
it over and instead bring cables in thru large PVC nipples. Do the
lightning abatement outside the house. If you do not change cables
often you could seal with spray in foam insulation.
Commercial installations do a similar thing with plastic entrance
pipes that can accommodate three hardlines. They have a rubber
membranes with split openings for the cable. Usually the entrance
has a cable box. But that stuff is real expensive so I make my own
for ham radio.

3. How do I get the cables into the weatherproof box? Should I mount
connectors [doesn't seem very good to me ... PL-259 exposed to the
weather], or are there weatherproof entrance fittings. One of the
cables will be 120 VAC, probably a heavy extension cord [for 12V supply
and the fixture to light the flag at night.
As has been pointed out, the not-so-expensive-box will be housing a
fairly-expensive-KAT500.
