What should I be setting TX power to?

The Meshtastic documentation says that max ERP in Europe is 27 dBm. But is this the number I should actually put in the TX power box? Because everything else I'm reading is saying that max power for broadcast is 14 dBm?

I have a 2.5 dBi gain antenna, and the country in question is the Netherlands.

Further context: I'm aware different devices have different maximum power output, and it depends on cable and antenna. Is the number in this box the power of the transmitter itself without factoring in antenna and cable? Does the firmware make sure the radio is not broadcasting above the regulatory power level?

I also wonder that myself. When discussing this issue with other community members, I was told that some popular devices like the T1000-e only support up to 22dBm (in the particular case of that device, it does not support antenna replacements, so it should be easier). However the iOS app allows setting 27dBm for devices like that one, which is confusing.
