There are littirally hundreds, if not thousands, of pieces that match your request, but one good starting point is the very nice "baroque guitar anthology" by Jens Franke and Stuart Willis, published by Schott. Four volumes of exquisite pieces, carefully sorted by order of difficulty. The first three volumes span the beginner-intermediate level, and the third volume ends with a complete and very accurate transcription of the sonata "l'infidèle" by Silvius-Leopold Weiss. Last but not least, each volume comes with a very good audio CD that is not only useful but also very pleasant to listen to.
Hope this helps,
