help choosing a database for real-time sensor machine learning stuff

hey, i just needed some help planning this out. basically, i have a little desktop app on my laptop i made which collects, logs and exports car sensor data. i am also then gonna make an android app which collects and logs gyro and accelerometer data.

now i just want to have these apps send the data to some remote database. i will have a jetson nano in the car (basically a raspberry pi) and it will take the data from the database and show it on a screen. both the car sensor and mobile sensor data.

i just don't know what kinda database approach i should use. i can use firebase and have both of my apps connected to firebase and upload data there in real-time. then i can program my jetson to retrieve that data and show it.

but i feel like there could be a better approach. is firebase a good choice here? later, i plan to export the firebase data in CSV and do machine learning stuff on it in real-time as well.
