Certainly wouldn't bother with the piddly electrolytics, but the big ones may be usable.
Hrm, ironically I have little use for larger electrolytics myself, so I don't even use the few I have collected over the years...
Mind that they probably need to be reformed (charging with limited current (a few mA?) to rated voltage), but other than that, can still be useful, yup.
If there's any tantalums in there (almost thought some were pictured, but I guess the "PTCs" on that baggie suggest otherwise!), they should be fine at any age. Can be tested in a similar way; tants self-heal in a way analogous to reforming.
What's the glass things in that one, tubes? Encapsulated capacitors? Also see ceramic tubular capacitors in there, those can be nice. Should be C0G I think? Or if not, then some variety of stable tempco (i.e., usually used for compensating inductor tempcos). Should be labeled much as resistors are, but in pF rather than ohms (multiplier = 1x pF's). Still usable today, nice parts, just, bulkier than MLCCs so can be hard to use outside of breadboarding, heh.
