Do we get the standard 27 points to spend on abilities as per the PHB, or do you want to use a different amount?

I'm thinking of playing an arrogant, foppish scion of a noble house. He was sent to Cedarport to learn some humility and 'real world skills' (as his father would call it) under the auspices of house Esperglow. As his father requested to test his mettle and make sure he returns to his house as a worthy successor, he was assigned to join the coterie of adventurers. I am planning to have him be somewhat arrogant and asserting leadership of the group, but being quickly and often put in his place by more worldly and skillful members of the group.
I would like him to start out as a rogue with the noble background, take the swashbuckler archetype (from XgtE) at level three.

Can you tell me if you can work with that? Also, what sort of house would be fitting to use and are there any race or class constraints associated with that? Do you have any lore on your noble houses I could go through to help me build my character's background?
