Hello Sieghard. Thanks for your advice.
About Raspberry Pi OS 64 bit. OK, I was able to install it on a Rpi 3 machine. But... It is highly unstable, if you do a apt-get update, after the Rpi does not reboot. Also many installed applications crash after few time and are much slower that the 32 bit equivalent. I was able to install fpc for aarch64 on the RPi 3. But... Only simple console application are working (application that uses threads crash). For GUI application, I was able to compile simple fpGUI and MSEgui applications, but only with 1 main thread. For Lazarus, like for the Raspberry OS 32 bit, I was not able to compile it and install it on Rpi OS 64 bit. So I have very sad news, I give it up at the moment for Rpi OS 64 bit. It is very rare that I take such a decision, I am a explorer_warrior after all. But in that case I have to be realist, Rpi OS 64 bit and fpc aarch64 are too unstable for the moment. All that said, if people was able to compile+run lcl or fpGUI or MSEgui big applications on Rpi OS 64 bit, I am more than interested to know how to do and what to change.
