Honestly -- your palate is pretty spot on for what i'd expect from a 10 year old Rioja reserva. The oak and vanilla are common notes due to the use of a good bit of new wood for most Riojas. From your notes it sounds like it probably is in a bit of a middle stage -- lost a bit of its fruit forwardness and not yet chilled out on the tannins to let more of the earthy notes (leather? is often one in rioja) shine.
To get a feel for how that wine would be young, sometime look for a cheaper, year or two old "Crianza" which is going to show more fruit (and sometimes more oak at the same time) but typically be less astringent. Here's a brief breakdown:

Dry is certainly a way to describe mouthfeel. Typically it's caused by tannins. Winos often say "grippy" or tannic.
If you like fruit-forward wines, there are a lot of fun lighter styles out there. Beaujolais (aka Gamay), Blaufrankish as gosthop mentions, Schiava, Lambrusco (some super quality producers of this historicaly maligned variatal are now around), Zweigelt, and many grenache/granacha .
