I do both! I blame my club dance intervals...
I started as a free skater as a kid. Fast forwards 24 years off ice I restarted skating. I only wanted to do free and had no particular interest in dance.
The club session I go to has 2x15min dance intervals and after a while it got really boring (and cold!!) just standing around and watching. When the club ran a brief learn to dance session a couple of months later (Riverside Rhumba!) I joined in and really enjoyed it - then mentioned learning to dance to my coach (who rather handily coaches both dance and free) and the rest is history!
Now I absolutely love it and do much, much more dance than free. I still try to jump etc but I've got such a mental block on jumps I'm completely stuck and find it very frustrating as I used to be able to do them as a kid. Doing dance gives me a fresh challenge - it can still be frustrating but I have no expectaions of being able to do it so can deal with frustration more easily!
Unfortunately the Adult International in Oberstdorf doesn't include solo dance but the answer to that is to do an artistic as you only need one or max two jumps and one or two spins the score is entirely on components.
There are some Adult International comps that include solo dance too eg
Dolomiti Adult skating competition in Italy and one in Dunkirk, France too - probably others...
