>Child inherits race of mother
This. Best way to have universal interbreeding between biologic races. You don't need to worry about problems with hybridization and you don't need to worry about issues with the mother being unable to carry the pregnancy or with egg formation or nursing or anything else.

>Child is a half-breed
Don't get me wrong, hybrids are fun to conceptualize, but they're a headache for worldbuilding. Albeit if you do want universal hybridization, you can *technically* work around it, but it's a pain. As an example from sci-fi, you can have all sapient races actually be engineered by a precursor race to be able to freely interbreed.

>Child inherits race of father
Objectively bad and only really used for goblin/orc rape porn

>Boys inherit race of father, girls inherit race of mother
Dumb

Also you forgot
>All children are artificial organic, magic, and/or material constructs designed by their parents
