Be carefull with your wording. This is very confusing.

This is ONLY Chonburi immigration I have experience with. Others may be different....and BKK don't care about TM30 at all

Opt 1...short stay and no contract (ie AIR BNB) Opt long term rental Contract. Option 3 Hotel.

If you as the tenant wants an extension and they can fine you, they will not try to involve the Landlord. The Landlord or host's involvement is USUALLY only required when there is no contract....such as AIR BNB or private short stay. It is the renters responsibility to report the TM30 and not the Landlord...I have come to understand.....They MAY as for Landlord ID though, wheb you do it yourself.

Yes that is correct. It is the skimmed down version which gives you only discounts on spas, etc, which is why it is cheaper. Still a good deal though. If you need the benefits then the 10 year for 1 mill is better.

yes if they allowed 3x 330k...would be a bit nicer...:)

I agree that would make a lot of sense....

Now that they have a 20 year for 1 mill, it is much better value. That is 50k or 1500USD per year. and you never have to leave, they do reporting for you, trips to the airport, spa, golf....for 1500USD....That is pretty good. With visa renewals, going out of the country, trips to the airport, I spend that easily in a year.....plus all of the hassle added on.....If I had the spare cash I would prob go for it...but for retirement extensions, if you never leave the country it is only 1900 baht a year...so the price does not really compare...but I am not 50 for a while yet....

This is correct. The need for a return flight within 60 days is very much required. It could be asked for at the airport check in or upon arrival into Thailand. So it really is best to have one....even if a waver can be signed to not have one.....although I admit that I never have a flight when I get a tourist visa and it has never been an issue....you never know if the immigration person you have at the desk is having a bad day or not....it clearly says for a tourist visa....accom details, onwards flight and cash in hand CAN all be asked for...for arrival into Thailand. The signed waver would not get anyone through the gate...

Most consulates allow the waver or a statement to be signed which is handy :)
