Choosing a Spanish team to support

I am looking for a team to support that is not Real Madrid / Barca.

I used to follow Real as a kid, but that was superficial and I don't feel any connection to them nowadays.

As I am interested to get into Spanish football a bit again, but I don't have the time to watch every team a few times, I would love some pointers to be able to limit my list to a few teams that I can watch and select from.

I normally enjoy teams with a cool rebellious vibe, passionate fans, no sugar daddies, not dominating the league (unless there is a great story of struggle behind it, like Bodo/Glimt in Norway), a homely feel at the stadium, socially inclusive and progressive, but not overly political, humble (working class) background. Obviously none of those is a must, but each of those makes the team more appealing to me.

Of course, they should play enjoyable and attractive football, but that doesn't necessarily mean attacking for 90 minutes, they could also play cerebral defensive football, and still be exciting to watch.

So teams I am considering are Athletic Bilbao, Real Sociedad, Atletico Madrid, Rayo Vallecano, Real Betis, Real Valladolid, Villarreal, Sevilla.

Please, give me some recommendations.
