I can definitely connect with this, I have the hardest time connecting with people. I will say that I have given myself a technique where I use humour to try and contribute a bit more to a contribute a bit more to a conversation. Well mostly sarcasm, like sarcastic observations.
And I tried to use fuller sentences and use a few variances of words, it is possible to make some changes to your vocabulary if you give yourself practice, and with yes or no questions it is okay to repeat the question. Example to being told the weather is good: "Yeah, the weather is good." Perhaps make another observation, and if your response may be within your interest you can give a basic lead up that can kind of summarise it to someone who may not know, not necessarily in-depth. Sure it can become awkward afterwards as you don't know what to say next, but it can feel like a step forward.
But I suck at talking to new people anyway. I had this horrible situation last year where I went to a social event with laser tag, but could talk to no one, and some friends I did have that were on the spectrum were completely okay with talking to new people. My interest has been in mythology which is nowhere needed for daily life and thus does not start except for niche situations, although I also know games and anime.
