many furniture stores will do a free consultation on one of your rooms.
i've done this a couple times as video calls. you set up an appointment and email them photos of the room and its measurements. then you get like, 1 hour of talking to somebody where they make a computer model of the room and how it would look with different items in place. this is a great way to find out, for example, what size dining table and what size rug will suit your needs without making the room too crowded, and then some design ideas you hadn't considered like, this spot really needs a mirror or that spot would be ideal for a large potted plant. i also received some tips on what fabrics were better for kids/spills, and what colors are "in style" these days. I sure would not have known otherwise!
i found it very helpful to come up with ideas i would not have had, and while they will surely fill your cart with ideas, i did not feel pressure to buy. go to the websites of any brands you already like and find the link for "free design service". idk where you normally shop but for example you could have room & board help with your dining room, then pottery barn with your master bedroom, then west elm for the living room. or whatever.
but if you want help on the whole house i agree, paying for a little professional time is worth it if it helps make you guys happier with the end result.
