I'll just contextualize the "1 light-minute" distance for everyone: ~18 million km. The extent of the gravity well for 1 Earth gravity: 1.5 million km ... or about 1/12th of that. Carrying that through to its logical conclusion has some pretty disastrous consequences for narrative & gameplay.

That number seems just a few orders of magnitude more severe than intended (which is why I used planetary radii earlier).

Meh, there's no specific numbers on anybody's sublight speed or weapon ranges so it doesn't particularly matter in my mind. It's a completely arbitrary number and it makes no sense for it to be the same size for every celestial body, but I don't especially care.

For narrative purposes, everyone needs 'a good chunk of minutes' to approach or depart a planet. No jump in, deploy drop pods, jump out.
