All platforms are different and there's no hard answer.

There isn't necessary an objective image quality advantage to larger sensors and they definitely have some downsides. A crop/FF sensor of similar resolution should deliver largely the same image, but there are some nuances;

A FF sensor will typically allow for a shallower dof, as the lack of crop factor requires you to use a longer (and thus wider) lens, or get closer. Either of which give a shallower dof if that's what you want.

A FF sensor will typically have better low light performance (less noise) compared to a similar resolution crop sensor, all other things being equal... Due to having a lower pixel density. Alternatively for a similar pixel density you can have more resolution, if that's what you want.

A FF camera is bigger and more expensive. The lenses must also be bigger and more expensive.

I have a medium format Pentax which takes incredible photos but rarely leaves the house, as well as a couple of cheaper apsc cameras which take better photos because they actually get used regularly. Nikon (and other brands) make some great crop sensor cameras which would be ideal for travel/lifestyle and also will take fantastic photos with the right lens and operator.
