Living in Tokyo for 6mo as a family-neighbourhoods and childcare

Husband and I have goals to spend 6mo living in Tokyo before our daughter starts elementary school (we are thinking January to June 2026). She will be 4.5 at the time. I'll qualify for sabbatical from work at that time and my husband will likely work remotely. Plan is for him to apply for a digital nomad visa with myself and daughter as dependents (we are Canadian). What I'm trying to think ahead on is where we may live and potential childcare so we can start saving appropriately. My main questions:

1. Any areas of Tokyo you'd recommend for a family with a young child? Commuting isn't a concern, but we want to live somewhere that has lots going on. We particularly like Nakameguro or the area around Yoyogi-koen (on the Shibuya side). Futakotamagawa is nice as well, I had a friend that lived there, but we prefer areas more "organic" vs centered around a mall (granted I've only seen that central area). We're going back to Tokyo this fall and thinking of using some of the time to explore potential neighbourhoods. I also acknowledge this may shift depending on where we land on question #2….
2. Childcare/preschool. My daughter is in daycare now and loves it. I want to make sure she has an opportunity to continue socializing while in Tokyo. Ideally we could put her in some kind of English preschool. The only one I've found that seems to offer partial years is the French-Japanese Language School of Tokyo (I'm aware we won't qualify for subsidies on a digital nomad visa). What other options are available?
