I also sat out one election here in CZ, but that does not mean that I was "fine with whoever wins". It was "I really cannot decide which of the two guys is worse and I need to survive either of them."
Fortunately the Czech president does not have that much power.
How about parliamentary election?
I have voted in all of them so far. Smaller parties = not much personal attachment + higher chance to find at least one that is, in that particular moment, more aligned to your interests.
In general, I believe that more choice is good and polarizing political systems are subpar.
