I'm completely biased but I am a fan of Toddington. Although without knowing what you want from a location beyond commute and schools there might be other places that suit you better.
Things that may matter to you in choosing a forever home location...
It's big enough that there's community if you want it but can opt out if it's too much for you. There are a core of people who organise community events and traditions, but they're usually pretty keen to embrace anyone who wants to get involved too. People pulled together really quickly when the pandemic started to organise a network to provide support to people who were isolating or struggling.
The GP surgery is decent. Purpose built. Currently a vaccine centre. L&D hospital is all of 10-15 minutes down the road.
There are more groups offering activities than I can keep track of in the free newsletter that gets delivered. The churches are responsible for some of them (and organising the newsletter - which sells advertising space for businesses) but not everything. Scouts, Guides, rambling, dance, brass band, football club, amateur dramatics (they have their own theatre)... I think there may be a group called ladies who lunch... Can't remember what else, this is probably a very poor sample!
Easy access to transport links but when you're away from the main roads it's peaceful. Never that far away from a footpath across the countryside. A pond. A few parks and children's playgrounds (one with outdoor exercise equipment for adults). Village hall was purpose built late 90s (I think) and is decent sized. Short drive to Dunstable Downs (and Whipsnade zoo) which can be brilliant for kite flying... various other National Trust places nearby. Also Woburn Abbey / deer park / safari park.
About 25 min drive to MK if you want city stuff. Or 10 mins to Dunstable/Luton. Train station in Harlington is Bedford-Brighton line and takes you to St Pancras in 45 mins.
It's under Central Beds council - my experiences of them are all positive. We get 3 wheelie bins (waste, recycling, garden) plus a glass box plus a food waste bin. Collections alternate on a 2 week rota. The nearest tidy tip was recently ish built and is really good. (I know bin collections are important to people!)
Garden centre with a restaurant just on the other side of motorway bridge (technically still Toddington apparently). Hopefully it will survive the pandemic. Hopefully all these things will.
In non-pandemic times, we have a summer fete, the band perform concerts (including a "teas on the green" one in summer), there is a well attended remembrance parade and service on the green, Christmas light switching on event, carols, Christmas tree festival, ad hoc events to celebrate special events or anniversaries, coffee mornings, TADS (Todd am dram society) do performances throughout the year and a Christmas panto...
We don't have a supermarket, but we do have some shops, bakery, takeaways, pubs, a library, a petrol station and a fire station. 
Anyway, I hope your family has a happy life wherever you end up.
