The one you will most likely be competing with is Paralives which has been in development since about 2019 and if their modding tools and the base system is any good it will probably take over the market.
InZOI looks like unoptimised unreal engine, with some weird idea to mix cutscences into the gameplay (and cutscences in which they are not even in the same environment as the action) very weird design choice.
My recommendation with you current proven skillset is not to head into this niche.
The only ones I know of are Paralives and inZOI

Paralives looks woke.
