Unless your Cat5e cables are running more than 40m long you should be able to do speeds over 1Gbps. Upgrading to Cat7 won’t bring any tangible benefit. However it is possible the cables in the walls are bent, damaged or absorbing interference from other nearby electrical cables.
If you want the full 1.5Gbps to your devices, both the router/modem AND the device must support this speed. Including the switches or similar on the way. Meaning if the ethernet port is only gigabit on either side, that’s as fast as it will go. (And upgrading everything to 2.5gbe will be expensive)
To diagnose the sub gigabit connection on your cat5e I’d recommend first making sure the jacks are terminated correctly and then testing maximum transfer speed with iPerf in UDP mode. If the connection speed doesn’t improve I’d look at upgrading cables. But only as a last resort.
