My last experience was Facebook contacted me a few times, which I blew off because I knew they would never hire me. Finally I told them "You know I'm over 60, right?" and they got off the phone and never called back.
I'm thinking about doing some part time programming on one of the job sites. I'm not thrilled with throwing PHP together, so I haven't tried yet, and program for fun now. In the last couple of pandemic years I've learned Rust, Flutter and lately Blazor, which I just gave up on today. I installed Nodejs to learn React this afternoon. I'm looking for a pleasant way to earn money building front ends.
I was aware of Mark Zuckerberg's comment which is why I brought up my age.
“I want to stress the importance of being young and technical,” he said. “Young people are just smarter. Why are most chess masters under 30? I don’t know. Young people just have simpler lives.” -- Mark Zuckerberg, Stanford University in 2007

Edit: I believe you when you say you don't age discriminate. That's because everyone is watching everyone else, including internal lawyers, to make sure you don't so as to avoid law suits. However, the person that called me was on a private phone call with me that wasn't being recorded, so they could get away with it.
Not trying to say its true or false... Just saying that it's no different than race or gender.
The second suggestion is present yourself as a solution to an employer's diversity issue. You would have to lean very hard on this diversity angle to get past the recruiter and the HR office. Once you reach the actual decision maker switch to the benefits offered by a long and diverse career.
Good luck
