Oh, can I ever relate. I bought a cargo bike back in 2018 when construction on our subway line meant I was looking at a much longer commute to daycare with my son. I opted for an e-bike since it was going to be ~15 miles carrying all of the gear a kid needs.
It's been transformative since it basically removes most excuses for shopping, recreation, etc. — we put more miles on the e-bikes now than our car — and we often laugh at the way your mindset changes. I currently have a heavy duty chain lock which weighs more than my lightest road-bike weighed unloaded, have been known to dig into the panniers and find multiple changes of clothes and toys for the boy, etc. What's really nice is durability: they make incredibly tough tires these days as long as you don't mind them weighing twice as much.
I must say that the times I've been on a real road bike have definitely left me missing that feeling — it's basically the bike version of the jokes about someone selling their convertible and buying a minivan when they have kids — but what I really want is to rent a nice road bike on vacation since the safe & fun routes where I live really don't need any extra performance (I don't want to be the spandex bro slaloming around kids at 30+ MPH on the shared trails).
