For everyday habits say 「習慣」; for the customs of a place, 「風習」; for old family or local rules, 「しきたり」. 「習俗」 itself is the written word for customs handed down in a region, as in 「古い習俗が残る」. For outworn, undesirable conventions use 「因習」. In formal prose 「慣行」「慣例」「慣習」 denote established practice, and 「恒例」「定例」 regular events. 「風俗」 still means customs, but since it also commonly refers to the sex industry, choose it with care.
