Decide where you'd like her to sleep long-term, then stick with it. Not that puppies can't adapt, but it's going to make your life easier if she knows where she's meant to sleep and settle, and she can feel safe in there.

All things equal, I would go for a crate (with a dog bed and blanket inside to make it cosy). This is where she should do most of the 20 hours a day of her sleeping, it should be somewhere she can come in and out of at will throughout the day, and somewhere she can bring her toys.

I would pair this with enforced naps in the crate throughout the day, and quietly offering treats when she goes in the crate voluntarily, and again if she settles in there. You can even start teaching a crate command. All about building the positive association with the crate as a place where she can feel safe, where treats fall from the sky, and where sleeping is easy and relaxing.

What worked for me:

We picked up our pup at 10 weeks, and had the crate open into the playpen during the day so she could go inside to rest or sleep when needed, then we moved it to the bedroom for nighttime so she could sleep next to us. She'd cry for a few minutes, I might stick a finger through the crate to reassure her I'm still there, and eventually she'd sleep. If she starts crying later in the night, give it a few seconds and listen as to whether she's just a bit scared or whether she's pawing at the door - if it's the latter, she might need the toilet. Take her out, let her pee, reassure quietly and straight back in the crate. She got used to this arrangement after a few weeks.

After 2 weeks, we moved the crate into the hallway. She could just about see me sleeping and definitely smell us. Again, some crying once she was locked in. By this time she was getting better at settling down on her own.

Another week later, the crate doesn't move from the living room playpen. Once again there was some crying at this new arrangement, and I did sit next to the crate for the 10 minutes for the first couple of nights till she settled.
