Since musical tastes tend to be idiosyncratic, maybe the best bet is to listen to a range of music on whatever streaming service you have access to. Once you've decided you like a particular piece and/or composer, you can search for the "best" recording.
I have a fairly extensive vinyl collection and I picked up >100 vintage classical albums from an online sales posting. The seller bought records in large lots and was searching for particular items. He jettisoned the rest of them for <$1.00/album. Admittedly, some were in bad shape but all recordings I bought were 40-50 years old.
