What kind of trees (conifers, flowering, fruiting, shade, etc.) and for what purpose? And is there a size you prefer?

The Trees forum is really the correct place for this question.......... :-)

If you want a flowering tree, consider Yoshino or Kwansan cherry. They are fast growers. Zelkova would also work, it is a large stately tree.

I know I don’t want something with dark leaves like a red Mapletree. I like trees that branch out and are leggy but I don’t want something that’s going to totally cover the house. I just really like a tree filled front lawn like you see on beautiful plantations in Savannah etc. but of course in northeast PA there will be no hanging Moss LOL

Dogwood, redbud, a greenleafed Japanese maple, Japanese snowbell (Styrax japonicus). Flowering cherries could work as well but be aware that they are prone to a lot of disease issues and can be rather short-lived as a result. Serviceberry (Amenlanchier) is another possibility.
