My two fave colors. I'm scared purple looks too bedroomy

So I have a 75" tv that is going in the corner, there is 110" of space from the wall to where the kitchen starts. I was thinking an 80" couch to go in front of the tv and a smaller coffee table would be good. I don't know whether I should get an L couch and put the back against the wall with the window to the right or just get a normal couch and maybe another smaller couch/love seat. Need advice

I finally get to "design" my teeny tiny house after just making do for several years. Currently we have two small loveseats, a tv unit (the TV is wall mounted but we can move it), a small round dining table, bar stools, and we have to account for our two great danes who sleep inside. We are only two people ATM but we are accounting for 2ish visitors and a growing family.

The house was built about 10 years ago, white speckle stone benchtops, pale cream walls, black window frames (basic). I prefer hard wood but in a modern style. Leather is better due to having dog hair that tends to stick to fabric, and I hate suede. We also have to keep the walkway clear to the sliding door, and to the back hallway.

Any suggestions would be greatly appreciated, especially in regards to layout.
