Hi
Though I am not in France have been lucky to be there but have traveled there several times so can more or less find my way around with some additional help of apps . Actually love exploring Paris on foot on a nice clear day it is truly memorable experience.
I relied mostly on the metro and once couple of times had a car however getting a parking space in central Paris can be quite a task so you may end up parking quite far away.
With bikes that is not the case though I never hired them myself.
Though I did consult the weather app however on a couple of occasions it rained suddenly when it showed sunny day.
This was particularly on the day we had planned to go to the Eiffel Tower.
On the day you are planning a trip to Eiffel Tower specially when the the sun goes down and the lights come on is quite a moment.
Hope you are lucky to get a clear day with no haze to capture good aerial shots of the city from the top.
