Easy way is

day tourist visa very easy to get a 60 day from the thai embassy all done online takes max 10 days then extend at a local immigration office fee 1900b if you do the paperwork yourself 2000 b if they do it for you will give you 88 days assuming you don’t wait until the last minute to extend
I did mine and two others at Udon Thani immigration office paid the 2000 they did all three extension the whole process took less than 45 minutes if you need more than 90 days the you will need to do a border run for each 30 period you can do this six times (but can only extend once at an immigration office ) meaning technically you can stay in Thailand for a total of 260+ days as a tourist if you start with a 60 day visa. Hope this answers your question obviously if your over 50 their are various 12 month visas that you can apply for based on your income
