Native French speaker here. In French the gendering of nouns themselves bothers me very little, because it just refers to an object. I don't really care about the chair being female or the tree being male, they can be whatever they want to be. :p A lot of animal names have a feminine form if you're specifically talking about a female animal, but other than that your pets will pretty much always be male. It's adjectives that bother me more - many change depending on whether their target is male or female. When I speak of myself I try to use adjectives that sound the same in both male and female form, and when that's not possible, I switch between both forms. I've noticed my parents have started to do it now too, which is pretty funny to me.

As for pronouns, in French the masculine form is the default - this pretty much applies to French grammar in general. As an example, if you have a group of women with one man, you'll refer to the group using the masculine plural pronoun ils no matter if you have three women or three million in the group - ils wins over the feminine plural pronoun elles because there's a man in there. Since French doesn't have any gender-neutral pronouns, I've pretty much just gotten used to using the neutral il to describe myself. To me, il at least implies some sort of neutrality, since it can be both male or neutral, but elle can't be anything other than female, and that's why I hate it. I do hope to see a more neutral pronoun set in French someday, though.

I've been learning German also, and like in French, gendering nouns doesn't bother me much, but that's partly because of how random noun genders can be in that language - even more random than French sometimes. I do know of a neutral form for singular third-person pronouns (es/es/ihm/seiner), though it translates closer to "it" rather than singular "they", and I don't know how common it is for someone to refer to themselves using this pronoun set rather than the typical masculine or feminine pronouns. (I don't live in a German-speaking country, and I don't have many friends to practice with either.) I don't mind these pronouns being used for myself, though; if anything I'd rather be called es or even er (male) than sie (female).
