It really depends where your house is at what kind if weather you gave personal preference also matters what kind if house it?

Home built in 1908. One story. Wood frame. We have replace rotted wood and kept it as original as possible. Do not know if we need a flat, satin or semi gloss. New trim work and framing that looks like 1900's appeal and plan to paint the columns in front as well. Thanks.

If the siding is nice and doesn't look peeled and is solid you could do a satin trim in semi gloss or flat on siding if there's lots if defects and satin on trim . Could you post a picture of your home ?
