growing parsley indoors for the first time, any do and not do?

Hey everyone!
I just planted this little parsley in a self watering pot and it is my first time moving my herbs indoors for winter.

In the past I always used hydroponic grow boxes outside during the warmer months, so I am hoping this will be a smooth transition for overwintering.
I followed the brand’s online guide and went with a large size planter to give the roots more room (and hopefully less drama).

Does anyone here have experience keeping parsley happy indoors through winter?
What kind of light does it really need daily?
Any tips for pruning or preventing legginess?
Do you fertilize during winter or let it rest?

ps really doubt about if water once a month like the brand promoted is real.
