5 GHz WiFi definitely has a shorter range than 2.4 GHz WiFi since shorter wavelengths (=higher frequencies) are being absorbed more by obstacles and even air.
Mobile networks vary way more, it all depends on which frequencies are available in the region and which frequencies are actually used by the mobile providers. 5G can be between .6 and 6 GHz (FR1 = frequency range 1) as well as between 24 and 40 GHz (FR2), the latter having way less penetration than the former so those frequencies won't be used as much since there would have to be an extreme amount of base stations to provide good coverage.
