There are 2 kinds of 5G, millimeter wave and non millimeter wave.

The one you are talking about is millimeter wave 5G.

The other one has pretty long range, goes through building, doesn't use up that much more battery and is overall a better technology (higher bandwidth, better congestion control and overall capacity for more connections in a crowded area, lower latency, etc.).

A sibling comment says the non-mmWave one uses the same bands as 4G, which would suggest it's not the version the OP is talking about

The 5G is pitched because greater speeds, and correct me if I'm wrong, but the millimeter waves are the reason for higher bandwidth otherwise it is similar to 4G that can peak to 1Gbps.

FR1 (the low band 5G) is capable of greater carrier aggregation and denser QAM modulation than LTE-A so it can achieve higher bandwidths than LTE-A under good conditions. It also has better latency and congestion controls which should provide a better general use experience as well as reduce degradation in heavy traffic. It also pushes more open hardware/software standards for base stations to reduce vendor lock-in.
