My first and only LF camera is a Norma, now I have backs for it to do almost everything from 645 to 8x10 and enough extension rails to get very large enlargement.
I think it is an ideal first camera, because there is nothing it really cant do if you just get the right bits for the system and you can experiment with all the movements that you can possibly ever need. I for one don't really have one genre of photography I like doing, sometimes I feel like landscapes and sometimes indoor still life and macro and the norma is never limiting.
However I have found that I don't bother to take it out with me for longer walks any more even though its very good once you get there, both the bulk and weight of the whole system is a bit much for me. I'm thinking of getting an A1/Alpina for that since then I can use a lot of the stuff for the norma.
