Hi!
I use WLM Plus myself and I love it. I set up the built-in true peak limiter to -1 dBFS and usually aim to -16...-14 LUFS long term per song.
Please note that only TIDAL really uses LUFS. Other streamers use their proprietary measurements, but they are +/- close to LUFS, so I use LUFS.
Here is a great page explaining it in depth.
And
this is a nice resource to test what different streamers will do to your master.
