Marry Macao people and apply for Macao hukou.

1. That's basically right. However, the order should be like this: you can apply for an endorsement of visiting relatives on the Hong Kong and Macao Pass, and you can stay in Macao for three months at a time, and then go back to the place where you registered. Wait three to five years, it's your turn to queue up, cancel your mainland account, get a one-way permit, and take a one-way permit to Macau to get a non-permanent identity card.

2. The endorsement for visiting relatives cannot be employed locally. However, some local units are willing to make "working paper" for you.

3. As the name implies, "one-way permit" means to go only once, and those who have not returned are officially called "mainland residents' travel permit to and from Hong Kong and Macao". Generally, mainlanders can apply for non-permanent identity cards in Hong Kong and Macao only after being approved to cancel their mainland status and change to Hong Kong and Macao status. Since it's a one-way trip, you can't go back and forth between Macao and the mainland, of course, because when you come back next time, you will get a local certificate from Macao and go back as a Macao resident.

Usually, people use it to travel. You use the Pass for Mainland Residents to Travel to and from Hong Kong and Macao to visit relatives. If you go, you have to come back, so it is commonly known as the "two-way permit".
