Double stroller, 2 year age gap

Hi! I’m looking for recommendations for a double stroller for an infant and (almost) two year old, that we can use as they get older.

I have a single stroller that I can use for the infant when I need to connect his car seat and just bring him somewhere. I’m looking for a double stroller that I use for walks around the block, trips to the zoo etc. I think I want a side by side, but am open to other suggestions. Does anyone have a similar age gap and a double stroller they love?

I also don’t want to spend much more than $300, but can look for more expensive options used on marketplace, etc.
