Since you'll be in your home country, might as well get a SETV, which is 1 month longer in total (60+30 day extension). You could also check for the STV (special tourist visa), which is even longer, but the requirements are much stricter, I believe. Make sure to prepare things much more in advance, to get issued the visa by your embassy before your plane ticket departure date (some people are not getting it in time). Same thing with the Thailand Pass (people aren't getting it in time as well). Although requirements will probably have changed by then.
Other option is the visa exemption, but which gives you only 30 days with the possibility to extend another 30 days for 1,900THB at an immigration office in Thailand. 60 days is not a lot. COVID extensions probably won't be continued in 2 months time.
Everything depends on what your current visa is. The Jan. 25 date is the last day you can apply. No matter what day you apply, if you are given the COVID extension, you will get a total of 60 days starting the day you apply. Some immigration offices give a "under consideration" stamp. This also counts in the 60 days total.
Even if you don't need one for your visa, it is highly recommended you get both a COVID and a standard health insurance. Unless you want to want to pay a 100,000THB or more hospital bill (or 700,000THB if you need surgery) if you get COVID or hit by a car.
