Am I overthinking the running vest/storage options? (casual trail runner)

Been researching different hydration vests/options for storage On one hand, I've read that it's worth splurging because you may very well end up using the thing for hundreds (thousands?) or miles. On the other, I see some people will just call it a day with a simple running belt.

My N NEVO RHINO (Amazon) vest delivery just arrived (5L space) and this is the first time I've ever actually tried one one and I'm already wondering why I never bought one ages ago because it feels pretty amazing; I've always been used to minimal packing (snack in pocket, no water; feelsbad on a warm day) or dealing with the mildly obnoxious bounce of a fanny pack worn across my shoulder.

This one costed $35 and right off the bat, I'm wondering if I should make the jump to a higher end vest because I suppose the above is true, I may very well end up wearing this thing a LOT. I'm considering something from Ultimate Direction but my dilemma is the cost/usage:

1. I'm still only a casual runner; I'd rather focus my efforts on sprinting / short&fast runs, not distance running/racing.

2. All my trail adventures involve a ton of walking/sitting so I have no actual need for quick access of anything.

3. Because of the location I stay here in LA/worklife hours, I often don't really have it in me to do much more than 10 miles or so; access to long/interesting trails are quite a drive away and I just hate being stuck in traffic after the week's work commutes. I'm really not sure if I'd ever need more than 5L worth of space. It seems the main struggle would be packing a UV umbrella but I tend to plan my trips to avoid peak sun hours.

4. Realizing that I may prefer a running/soft flask (assuming that's what they're called) over a bladder so if I do buy one, that'll cut into the costs and sort of negate the budget facto of the $35 model I bought.

Unfortunately can't judge the quality/durability of the thing & compare to a more "premium" brand but if it can hold up, it feels fine to me. Thanks for any input. : ]

EDIT: Thanks for the replies, I'll work with this one for now, learn what I need to pack, etc.
