The best family games like Banjo-Kazooie are Yooka-Laylee, A Hat in Time and Donkey Kong 64. Below are 8, each with the reason it is here — and, at the end, what filtering to family costs you.
Filtering to family means the game has to work for a child and an adult at the same table without either of them being bored. That is a much harder design problem than a difficulty slider.
What you get: Something you can put in front of anyone. The best family games make the skill gap not matter rather than pretending it is not there.
What made Banjo-Kazooie worth playing in the first place is covered on the full list. This page is the family part of that answer, and only the family part.
By much of the same team — the direct attempt at a successor.
The one that actually recaptured it, with better movement than the original.

The collectathon with genuinely great writing and level concepts.
A modern, straightforward take on the same structure.

With mixed ages, co-operative usually wins. The competitive ones that work are the ones where being in last place is still entertaining.
By hand. Each pick was written for the full Banjo-Kazooie list first, on what the game actually does, and this page is the part of that list that is family — never a genre tag lookup, which is how "best racing games like Super Mario 64" used to be a page on this site.
