As always it depends on your goals and budget. I am fairly shocked at how good a modern phone camera can be for family, landscape, portrait, wide angle photos, even in low light. Sports and wildlife are two areas that really require more camera and for me, the mirrorless cameras from the last 5 years are getting it done.
Quality F4 tele glass and a crop sensor camera with excellent auto focus are sort of a sweet spot for sports and wildlife in terms of cost/benefit. If $$ is no object, get a 2.8 Tele and never look back. I like what Sony has done with both their lens selection and also the A6400/A6700 cameras in recent years. Worth a look.
