, I would think if you mention retirement visa, this will speed up your search. Also, it helps if you can go with a Thai partner (But I don't think this is the case for you). Also, the bank will check your passport for visa etc. But it also helps if they can see that you come to Thailand frequently. If buying the insurance helps to speed up the search, no harm in taking it. Some banks are more amenable than others. Search this group, there have been many discussions on people's experiences.
