Welp, I can't think of anything exactly like you describe right now.
In any case, you get to pick 1 feat to start off with, and will gain more at a relatively slow rate as you level up.
You have the option of buying 2 more feats right now by taking an equal number of flaws. But you cannot use this option after character creation, and feats are often worth more than flaws, so I highly suggest it as an option.
Then I would grab lock picking and a climbing feat for large foes the main flaw being theres a larger chance to be grabbed or crushed attempting it along with being a easy arrow target. Just where do I put them.

Lockpicking is a skill rather than a feat, just invest some of your many skill points into it.
Climbing onto a creature larger than yourself is already an option without any feats. If you eventually want to be good at that, invest in the Ride skill. Don't be surprised if it takes a while before you can reliably pull it it off.
For actual feats, I seriously suggest taking a look through the ones I already listed. For more options, look here Source 5w
That isn't all of the feats available, not even close, but those are the basic ones.
Oh! Just thought of another feat you could make use of. Deft Fighter. Adds your intelligence bonus to your AC so long as you wear no armor or very light armor.
Its a passive bonus, so just write the feat down somewhere on the sheet, (I put mine down in the stats section) along with a description. I'd suggest using the following text for said description: "Can add Intelligence modifier as a dodge bonus to AC, anything that causes you to lose your dexterity modifier to AC will also cause you to lose this bonus. This bonus cannot be applied if wearing armor or shield with an Armor Check Penalty."
After that, just tack on your Int modifier as a dodge bonus as described (It will add to standard and touch AC) If your Intelligence modifier changes, don't forget to update that too.
Note that the no armor check penalty limitation keeps you from using studded leather armor, so swap that out for regular leather armor.
Okay, so that's one feat chosen, you can get up to two more. I listed a couple of particularly good options on the last page.
Perhaps I wasn't clear, The extra feats available right now are only available right now, and several things you might want to do are very difficult to manage without the right feats.
Take for instance fighting with two melee weapons, one of the best offensive options for rogues. Without the two weapon fighting feat I mentioned before, the penalties for doing that are quite prohibitive.
You do get more feats later (1 at level 3, 1 at level 6, etc.), but generally speaking, the more you take now, the better off you are. Because no matter how many feats you get, there will always be more out there that could be of benefit
It is also worth noting that level 6 is a very long ways away in this game. Your highest level companion just turned level 5, and he's been playing for years.
