A useful way to see all the dances in the Bay Area in one glance is this combined calendar:
https://sites.google.com/view/bacds/dances
(if you want to simplify the view, you can select the calendar icon next to the word "Month" and deselect some of the entries - e.g. deselecting Bay Area Irish Dancing will remove all the Irish dances from your view)
You can always find this calendar by going to bacds.org and selecting the entry All contra, English, traditional square & Irish dances in the Bay Area in the Calendars dropdown menu.
For Cajun & Zyedeco, check https://sfczcalendar.com/.
Ashkenaz (Berkeley) often has Cajun/Zydeco, Balkan, Latin, and other types of dancing.
For Scottish country dancing, see https://rscds-sf.org/classes/ and https://rscds-sf.org/calendar/.
Additional links are available at https://bacds.org/links/.
There is a SF Bay Contra Discord server that is useful for planning carpools & meeting for meals before, various discussions, etc.
