Fee policy means outbound fee policy, yes.
Inbound policies are a thing available in LND only, I think, but there is a BLIP: https://github.com/lightning/blips/pull/18
Other implementations should enable this, but you know CLN, it is always the last one and usually it comes late. Another reason not to choose CLN added to the long list.
For setting inbound fees graphically I know of LNDg in their advanced settings tab, which is also a good rebalancer and has a good interface (only for desktop).

I see. That https://github.com/lightning/blips/pull/18 is not merged since 2022. Looks like there is a simpler and less disruptive way to implement that and it is to ask the peer on the other end of the channel to lower their fee and you will pay the diff to them. For example, assuming a channel between A and B:
A (outbound fee 1000) ---> (inbound fee -100) B
would be the same as:
A (outbound fee 900) ---> (no inbound fee, B pays 100 to A after a payment goes through) B
In the second case a greedy and mean A can increase the fee from 900 to 1000 shortly after and get 1000 from the sender and 100 from B. But that is equivalent to the first case where A can increase its fee to 1100 after noticing B set -100 inbound.
Inbound fees have to be supported by all softwares that support sending payments over LN. I wonder how many support that currently.

As I said, losing is imposible because it is a discount. But if you don't believe me, let Lighting Labs tell you so:
