A 32mm plossl will give the widest FaoV possible with that scope (about 0.8°).

And an 8mm will usually be the maximum magnification you will be able to achieve. I actually live somewhere with fairly bad atmospheric conditions, and have only been able to use an 8mm twice. I usually max out around 180x. So maybe stick with a 12mm or 10mm as you high power eyepiece for now. You can always get a higher power eyepiece in the future if you think you atmosphere can handle it.

And then get a few eyepieces in between. So maybe consider a 32mm plossl ($35), the 20mm and 15mm “redlines” (Same or a bit better and “goldlines”, I bought mine from AliExpress. try to find them between $25-$35), and then this 12mm Starguider ($65).

You should be good to go with those 4 eyepieces.
