I'd recommend the Haydn Cello concertos. Haydns are easy to enjoy. Yo Yo Ma has recorded them (they are ADD). A terrific recording in my opinion is by cellist Steven Isserlis (DDD). For 'less' instruments you might like the Beethoven works for piano and cello. There are many great recordings.. I've got a few of these and a newer one I like is Alfred Brendel/Adrian Brendel. I also 2nd the Starker Bach. To save money, I like the suggestion of using the library before you buy. Good luck.
