Living Room Furniture Sets

How much walking space/clearance do I need when laying out living room furniture?
We are moving into a new, unfurnished house — it’s a big blank slate! I am excited about decorating everything, but I don’t want to cram too much into the space and make it feel small. What’s a good clearance around furniture, so that it doesn’t make for a cramped waking flow through seating areas?
Specifically, how much space should there between a coffee table and the couch? And how much space should be between a built-in wall unit and a couch that sits perpendicular to it? The doors on it are 12″, so I’d need at least 12″ to allow the doors to open; I don’t think just 12″ is enough, but is 20″ too much?
TIA to everyone!

for all new furniture in the living room right now we have white suede furniture so we are getting rid of it as we have a 7 month old baby, but
i’m wondering when shopping do we look for anything, ex, certain colors, textures, shapes, etc, for instance dark brown leather
thank you in advance for any and all help. have a great week.
p.s. we will be getting everything, sofa, love seat, chairs, coffee table, thank you.
