should i adopt? which one?

I am planning to adopt a kitten but i am not sure if i should because i have never had a pet before.

I can't foster but i take care of a stray in my neighborhood so i do have basic idea (food, litter, medical issues etc)

i have never met a kitten before believe it or not so this will be my first time. I am attaching pictures below so can you guys help me figure out which one to take if i should?

my family is not sure either as my brother keeps saying kittens can be loud demanding and messy but i am not sure if he is saying that just to demotivate me

please do share any advice or experience that i should know about Kittens which will help me decide.

my main concerns: 1. what if I don't adopt it and its given away to shelter or someone who won't take better care for it than me?

1. what if I am not able to care for it properly as i don't play around too much and stress it out? she is a Persian so i am not sure about her nature?

2. what if my stray ends up having kids at my door one day? i would never want to abondon her kids (which makes me want to wait for a while before adoption but i don't have enough time as owner is leaving her behind in 2 days)
