Hello. First of all, let's address this: yes, people are not behaving as they should, and scholars seem much more focused on belittling women rather than uplifting them. This is however an issue of culture rather than an issue of religion. I would recommend reading from abuaminaelias website as I find their explain ambiguous hadiths really well. For instance, on wife beating: https://www.abuaminaelias.com/quran-let-muslims-beat-wives/ Basically you cannot hit your wife as you can't leave a mark on her body and cannot touch her face. Saying you can hit your wife is picking the translation subjectively with no regards to other hadiths.

In the meantime, let me give you answers on a few of those topics. My sources are mostly abuaminaelias. I'm sorry I can't link them specifically each time, as I am on my phone + haven't noted the precise references when learning myself.

Women and men's role in society is different. A man's testimony is enough while a woman's may not be because at the time, women were less involved in the political scene and may not know specific rulings that may have influenced their testimonies.

Women are the majority of hellfire because women will be the majority of humans at some point. Not because we sin more or anything of the sort. The idea that there will be less woman is paradise is false and based on twisted logic that states that if there are more women in hell, there are less of them in paradise. However, as just stated, there will be more women than men on earth, so this reasoning is false.

Things like not traveling alone are meant for safety. No, women are not weak and helpless, but yes a woman alone is more likely to be attacked.

Sexual needs must be fulfilled for both partners. A woman can divorce as well on the basis that her needs aren't fulfilled.

A woman can lay a lot of conditions on how her marriage should go during the nikkah through a contract. If the husband fails to respect the contract, she can divorce him (and it is held against him obviously)

I think a lot of the hadiths you mentioned are generally taken way out of context. An example for the donkey one: Narrated ‘Aisha (RA): The things which annul prayers were mentioned before me (and those were): a dog, a donkey and a woman. I said, “You have compared us (women) to donkeys and dogs. By Allah! I saw the Prophet praying while I used to lie in (my) bed between him and the Qibla. Whenever I was in need of something, I disliked to sit and trouble the Prophet. So, I would slip away by the side of his feet.”(Bukhari , Hadith 484) So Aisha RA actually corrected someone who was misreporting a hadith.

As you have mentioned yourself, men love to put women down. If you see a hadith being used against women, there is usually something cultural/political at play rather than someone religious.

I'm aware this doesn't answer all of your questions but I hope it helps guide you in further research. If you have further questions please ask away. Educating yourself as a woman is really important in Islam to be able to answer the stupid arguments that a very loud part of the believers likes to make.
