Assuming organisms adapted to live there, it would be harder for them to reach escape velocity to leave their planet. Is there a cut-off where known physics says it’s impractical to leave a planet? Ie the most powerful practical fuel wouldn’t be enough for any mass to reach escape velocity?

There's a table in that link of how much reaction mass is needed to reach orbit. At 1.5g it requires about 500% as much rocket as Earth. At 2.5g the number is ... much larger.
