I chose "Natural Chokepoint" and "Fort in Hostile Territory".
When ending a turn in enemy territory I always build a fort, because 1) the AI seems more reluctant to attack forts and 2) there is always open ground around forts, which suits my cavalry and archer-heavy armies better than being attacked in the middle of a forest.
Natural chokepoints are, of course mountain passes or narrow patches between natural obstacles (like southeast of Antwerp). I also use them to block land bridges. This doesn't work with all land bridges, but it works on the one connecting Jutand with Fynen (Denmark), so you can effectively lock the Danes out of Europe.
I didn't tick "Inland Garrisons" because the only inland fort other than the obvious chokepoints is my "Messina Fort". When I first got the game, I was disappointed that the famous Crusader port was not there, so after conquering Sicily, I always build a fort in its location where I gather units bound for the Holy Land. Call me sentimental...
I never liked merchants much and I've never used them more than sporadically, but I might consider doing the "merchant outpost" thing in future.
