yes you can get brown sealant , probably best to put it on after you've stained wood as stain doesn't stay on it that well

im asking if i should get the silicone one or the non silicon frame sealant ?

both sound suitable for wood and outdoor use

you need a non silicone based product. Silicone is not designed to be painted / stained and, in fact any paint or staind will not adhere at at all. You need the acrylic based product. On the tube it should say 'overpaintable'. Needs to be a good external quality.

Frame sealant should be fine, as said dont go from silicon even though its better for most jobs, paint/stain doesn't adhere to it

It shouldn't costs anymore than £2-£3 plus the mastic gun

for hidden areas would silicone be a better option? longer lasting

No. external quality overpaintable sealant is fine. They bothe do the same job in terms of keeping the moisture out.
