You're on the right track. Get the highest temperature rating
available (which is probably 125C), buy only caps manufactured by one
of the known-good manufacturers, and select from a parts series the
manufacturer designates as "high reliability" (or equivalent).
If it is a solid tantalum, I like the Vishay 199D Series. The AVX
TAP Series and the Kemet "T" Series ("UltraDip II") are also high
quality. (This list isn't exhaustive -- these are just the ones I've
had occasion to qualify.)
