There are loads of priests who publish their homilies online, and I’m sure they realize that others pick out some for personal use.
Parishes subscribe to various “homily Helps” materials, We have 3 of those subscriptions.
What Father elects not to use, the secretary publishes in the bulletin. We pay a user fee for these.
I’ve had priests read form their notes before. Just as some people can’t tell a joke without goofing up the punch line, some people tend to skip a salient point in the story and then are upset when it didn’t exactly turn out the way they expected, so they write out their homilies and read.
Yes, you can see the people;s eyes glaze over. But imagine if your could not see…you would still, as a person in the pew be expected to take those words into your heart and hear the lesson. Granted. Some lessons are not real deep, others, you need to be really well catechized to follow. That’s the diversity of the strengths of the priests we are blessed to have. Rather than be so critical, try to find a way to really engage with his words.
You might even say to him personally, later on, “father, I love it when you speak off the cuff…could you speak from the heart sometimes? I feel like I can learn a lot from you and your personal experiences.” He might like the affirmation. You never know.
As to the other things. clearly you are NOT happy. Some of those things are going to bug you until you decide it’s not near as important as worthily receiving Eucharist.
Find a parish to your liking if you simply can’t stand it, but really…I wonder what the priests would say about us flawed parishioners…

Would they say we were just sitting there waiting for some flaw or mistake in the liturgy? Or would they say were well attuned and well disposed to receive?
Something to think about. I hope you find peace, and the welcoming arms of Christ when you go to Mass again. Pray for your priest. It’s a tough job, requiring lots of formation.
And also, the prayerful support of his parish.
