here are common requirements

There are only 2 known Thai embassies in the world that will issue a multiple entry non-O visa based on marriage. The first one is Savannakhet, Laos and the second one is Yangon, Myanmar. With a multiple-entry marriage visa you receive a new 90 day stamp every time you enter Thailand.

If you are asking about a re-entry permit, so your entry stamp is not cancelled when you leave, then you just need to apply for this from your immigration office or get it at the airport on your way out. This will not add any time to your entry stamp, and you must be back and apply for your extension before the original stamp end date.

Most immigration offices will require a TM30 in order to apply for an extension. This would come from the person who owns where you are staying as it's a legal requirement for them to file a TM30 within 24 hours of your arrival.

Whenever I use AirBNB and know that I'm going to need to go to immigration, I always message the host before I book and ask if they will do a TM30. Hotels it should be easy, just ask the front desk when you checkin.

If you are renting a condo I would check with the owner or agent to make sure they will will do it and send it to you.

The DTV is a tourist visa, so it's going to be almost impossible. Your options are to get a residence certificate from immigration and then try going to 30-50 bank branches and see if you get lucky, or find an agent that can help you do it for around 5000 baht.

Yes, the re-entry desk is open 24 hours at Suvarnabhumi. If you go through departure zone 2 it will be after security but before passport control. If you go through any other departure zone you will need to loop back around after passport control. Just mention to them that you want a re-entry permit and they can direct you to the correct place.

It's 1000 baht if you bring all the documents and a photo, or 1200 baht if you don't bring anything but your passport and they'll fill in the forms and take the photo.

Visa exempt will give you 60 days and you can apply one time for a 30-day extension, so that's already more than 60 days.

What visa you should get is an irrelevant question. You need to look for what visa you qualify for. It's possible you don't qualify for any visa, and you cannot stay in Thailand as long as you want.

That depends completely on which extension you are applying for, and which immigration office you are using. Each office sets their own requirements, and each extension type has its own requirements that vary by office.

You just go to normal passport control and hand over your passport and boarding pass, and receive your 60 day entry stamp.

No, it's not true. The only people who can answer would be your local immigration office. Some require you to report every time you return, and some only require it if you leave Thailand and return.

There is no 60 day extension available unless you have a Thai wife or Thai child. If you come as a tourist the only extension you can get is a one-time 30-day extension.
