Encrypt your SSIDs with a pre-shared key (WPA2-PSK or better, WPA3-PSK) that only you and your immediate family knows. Do not share your PSK to anyone else. If you frequently have guests over that needs WiFi, allocate a separate Guest SSID with its own PSK that you can share. When they leave, disable the SSID or change the PSK.

MAC filtering is weak as devices now have the ability to 'fake' and/or randomize their MAC addresses.
