But then worry I'm going to end up with a disorganized mess of a collection with thousands of random coins with no clear value when I am done.
Been collecting since 1980. Over 11,0000 coins. Virtually no "completed sets" and no detectable pattern so far (I find "gotta-catch-em-all" set completion very uninspiring, myself). And enjoying the hobby immensely.

As for "value", if you mean monetary value, then I hate to break it to you, but forming coins into "sets" does not add value. It's one of the weird, paradoxical, perverse facts about this hobby: sets, whether they are mint-assembled, dealer-assembled or collector-assembled, are worth more (monetarily) if you split them up before selling them.
If, on the other hand, by value you mean "collector interest", then they already seem to have very little of that to you, because you don't sound very interested. Once a hobby starts to become like work, it's time to reorganize your approach to that hobby. Remember, this is supposed to be
fun and
interesting.
How to do that? Find something else about the hobby that interests you, perhaps: world coins, mediaeval coins, ancients, tokens, medals, paper money... there's plenty of possibilities. Or, try linking your hobby to any other interests you (or your family) might have. Like history and/or genealogy? Then maybe coins from the countries your ancestors came from might be of interest. Like cats? Start an open-ended thematic collection of coins with cats on them. Sports fan? Coins and medals depicting your favourite sports could be the way to go.
Remember, there are no rules. So long as you're enjoying yourself, you're not "doing it wrong".
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
