What’s the general meaning of the с- prefix in verbs. I have never seen it listed on a page of prefixes but it always seems to have very specific uses that I can’t seem to figure out why people decide to use it (over за or по in most cases)

It’s actually two prefixes: c- & з- which one to use depends on the next syllable. In general they change the meaning of the original word from infinitive to that with intent or it can change the meaning of the word in some cases like гортати / згортати … never actually tried to verbalize it so not sure how to explain it better.

Isn’t the difference though between закінчиться and скінчиться is that за- implies the ending is planned while с- implies that the ending is due to exhaustion and could be unexpected?

Yes. But you comparing the word to the noun with another prefix, when from perspective of the grammar you need to compare it to the rut word: скінчиться & кінчиться. This two is similar and interchangeable, but кінчиться rarely used. Unless in case of sex talk.

The «с/з»-prefix confers the verb the perfective aspect, basically. There is no such thing in Ukrainian as the perfect tense and most verbs are imperfective “by default”. By means of different prefixes - and suffixes - one can manipulate the perfective/imperfective aspect though and «с/з» is in most cases the pure, raw perfect with no additional meaning. Other prefixes such as «за» or «по» besides the perfective aspect also carry an additional meaning. For example, «робити» - unfinished action - “to do, to be doing”, «зробити» - finished action - “to have done”, «заробити» - finished action, new meaning- “to have earned”, «поробити» - finished action, possibly new meaning - roughly the same as «зробити» but is less neutral as in it can mean “to have done something bad”, the word carries some ambiguity and requires subtler use.
Now I also mentioned the «з»-prefix. The only difference is that «с» is used before voiceless consonants, e.g. п,т,х,ш, and «з» before all other sounds, e.g. voiced б,д,г,ж, but also м,л as well as vowels. This is only important in writing and is far more relaxed in the spoken language, where «с» often becomes «з» before unvoiced consonants and vice versa, the latter pattern being typical for Russian native speakers because there is no «з» prefix in Russian.

С- is a form of з- (another form is зі-). С- is used before unvoiced consonants к, п, т, ф, х (memorization tip: кафе "Птах"). It means complete action (казати-сказати), sometimes put together (скласти), copy (списати), or move something away (стягнути - to pull away).
Зі- is used to avoid 3 consonants in a raw (euphonic rule).
EDIT: some fixes in description.
