I agree about the tripod. Take one.
But consider what you might use it for, that your pack frame will not do. You may find that you don't need a tall tripod. Something that can sit in a few inches of water, or get down close to the ground. This could save some weight and space.
For a taller perspective than your pack frame, you may be able to use a walking stick/monopod. You will probably be carrying a walking stick anyway, make it do double duty.
Everything is a compromise, when you are carrying everything on your back.
For your first few dayhikes, pack everything, as if you are going on an overnight trip. It will give you a chance to work out the bugs before going out for a long weekend.
