Juliann, I'll post a site from the UK that has pictures of various types of gardens. This link goes to their Cottage Garden which they say is "contrived to look uncontrived". There are many other types of gardens there that might provide inspiration. Which plants you choose depends on which climate zone you are in. I'm in zone 3 so am somewhat limited in what I can grow. I'll post a pic of what I call my wild bird garden. It's an area in my large garden that has the birdfeeder and birdbath. I allow the flowers to go to seed for the birds so they self-seed. This area has changed over many years altho I initially seeded shasta daisies (the butterflies love them) and yarrow and planted a few established perennials. The yarrow seeds I planted were a mix of red, pink, and white, but the white resembles the wild yarrow we have so we pull it out and it's mostly now only tones of pinks and red. There are also Lamb's Ears because they seed all over my garden but I leave them in this wild area (the bees love them). There are a few other plants, a pink mallow that's 'weedy' but it fills the space and is quite pretty and we also have several lilacs here. Near that area there is also a drift of common old irises which we've allowed to spread. They are in the lower part of the rockery and I will eventually weed some of them out as the bloom time is not very long. If I were deliberately planting a wildflower garden I would not buy a wildflower mix as there could be invasive plants in it. I planted a mix about 14 years ago and still have Dame Hesperis (Dame's Rocket) altho pull out many every year and try to dead-head them ASAP before they seed. It's quite a weed in warmer climates. I would choose seeds of plants I like that are hardy but not invasive and mix them together. Another option is to plant in swaths with various plants and grasses hardy to your area. Keep in mind the moisture requirements of the plants as you decide. The area where I have shastas, mallow, and yarrow needs little watering and only a spring weeding so is easy care.

Tile breaks when it’s insufficiently supported. That’s a manufactured home’s stock in trade. It’s is not built to stick built standards of support and rigidity. Which is why they use vinyl and laminate in all of them. Choosing tile is setting yourself up for failure and additional expense to replace it all.

Picking up and putting away boxes and random small items in the entry is free and would make it more attractive. Perhaps you just moved in and haven’t found a place for everything yet? If the random items are intended to be decor, they’re not really working - for instance, in picture #2, the tiny bench on the left and the little ladder on the right. A little story: when I got married 50 years ago we were very poor. I thought if I bought 10 things for $1 each and used them as decor, I was doing good. Over the years I have discovered that $1 items are cheap, look cheap, and will always be cheap. It’s better to buy one $10 item rather than ten $1 items. If you could spend $100 on one item in the entry, buy an entry table or a good rug, about 3x5. Check Wayfair. It looks like you have a nice home.

Your facade is not flat. I'm not a fan of the gray, but you coukd brighten it up with brighter shutters. It's hard to get a good read on the gray, My neighbor has a soft, grayish turquoise for their shutters. It's classy and brightens up the gray. The trick is to avoid any hint of neon.
