I'd be keen on playing a knight as well really, though I'd note, even if not in my interests, the pirate thing is probably the easiest for diversity of concept and also single focus. You're on a ship, you do pirate/privateer things.
I'd otherwise, for a knight campaign or court or some such, suggest basing things out of Caerleon, it's the capital, it has a lot going on, it gets a full page of detail, and there's even a map of sorts.
Beyond that.. I'd actually ask/suggest going for more than 100 point starting, and in this case that has nothing to do with a like for powerful characters so much as a like of ones competent compared to the setting.
7th sea sort of has three main problems (or, at least, most people I talk to have agreed on such), that love of 7th Sea makes for people putting up with.
1) the metaplot from Die Kreuzritter onwards (but that's ignorable)
2) the named npcs in almost all the books are on the whole statted on a scale that as a player you will, especially at the slow rate characters in pbp advance, never touch.
3) Everything is hilariously expensive to the point that you actually hobble yourself pretty hard to take a swordsman's school or sorcery, especially when there are so many different knacks in base skills needed for so many different things (behold athletics alone, and despair. Or courtier). Especially as a swordsman, someone who just spends straight on relevant traits and skills will generally be as good if not better at ass kicking.
Most games I've played in, to get around that, or to at least provide the chance of getting to one day feel the journeyman level of whatever thing you ran with, or make it less painful to go for full sorcery or swordsman (or god help if you if you looked at the various npcs that have both and thought "I could do that too!", both) go for creation point spending from 175-250, while keeping the nothing above 3 limit so that no one borgs into 5s of whatever or starts as a journeyman in something or etc.
It's just a personal view I've had and found in a few others, figured to mention.
