IMO, most of the real improvements are seen going from $300-ish to $1200-ish. Going higher doesn't give you more features so much as more quality and durability

IMO, most of the real improvements are seen going from $300-ish to $1200-ish. Going higher doesn't give you more features so much as more quality and durability. In my experience, if you ride a lot of miles consistently on a cheap bike, parts will wear out or break pretty fast. Especially if the terrain is at least mildly rough, as found on most commutes and country roads. Cheap wheels go out of true easily and before long are often too bent to be able to true by spoke adjustments. Cheap tires wear out fast and puncture easily. Cheap brakes wear out and go out of adjustment fast. Ditto cheap shift gear. I've broken pedals too, and I don't pedal all that aggressively. Really cheap stuff tends to be excessively heavy too, which can be a drag on uphills and when you need to carry it. Yours looks like a perfectly fine commuter bike to me. I'm not familiar with the wheel or shift gear classes, but if it gets you where you need to go without wearing stuff out too fast, by all means no need to spend more.
