why we don't have a standard default CLTV delta for all implementations?
Because each developer chooses a different value. It's a tradeoff between multiple factors.
why each one have that specific amount of blocks?
The CLTV delta is used so that if your peer surprise settles the HTLC, you have some amount of time to react. The amount is a tradeoff between HTLC stuck time and the possibility of losing funds due to your outbound HTLC being settled but not your inbound.
what happen if I have a LND and/or a CLN node and I set to my channels 73 blocks for CLTV ? Or any random number.
It works as usual. Defaults != requirements.
does this CLTV can affect force close channels?
If it's too long it could lead to stuck HTLCs. So possibly.

Also, I'd recommend not setting it above 144 blocks (1 day) since it causes inconvenience and it could possibly cause stuck HTLCs.
