Reading your post gave me chills. I was the youngest child in a large family, all boys until me. I grew up in an extremely sexist misogynistic family. I remember clearly in grade school, my mother would fry eggs for my brother, I'd ask can I have an egg mom, she'd say no, I'm busy. I'd say but mom you're standing at the stove cooking eggs?? She'd say well your brother plays sports, he needs eggs, you can make yourself cereal. She'd make me walk miles home from school, brother had sports practice across town and had to be picked up. Similar to things you've mentioned, whatever they did was fine, if I did exact same thing I was wrong and punished.
One year I played basketball in school, my mother came to one game late in the season, arrived after I was done playing. I never signed up again, nobody cared and I was left walking home miles in the dark.
I remember teachers noticing my last name, asking me are your brothers x,y, z? I'd say yes and teacher would gaze on me sadly.
One day my mother told me there was something wrong with me, probably bc I was a girl, not a boy, boys don't have these problems, you're making them all up for attention etc etc. My bothers were WILD as kids and teens and I was a quiet bookish girl but I was always on the wrong foot in my family. Brothers became their own little clan I was excluded from. I don't think they meant to exclude me but they were basically shown that was the dynamic and rewarded for it so of course they went along. I don't blame them at all as it was taught not inherent.
Fucking sexism and misogyny are poison, it deeply affected me and still does. I cut my family out of my life when I was an adult. You see the pattern happening and still have time to stop it and show you at least love your kids equally. Please don't fail your daughters like my mother did.
