I think the PST G2 1-6x is a very nice optic for the $ that will fits what you've described well. It compared well to the Razor for non duty usage. Around $500 new sometimes on sale. Glass is good, not just for the $.
Skip the old PST gen 1, 1-4x version as the glass is so bad it will make you claw your eyes out after a few minutes of usage.

That said, here is a friendly recommendation to run that carbine irons only and focus on prepping your home, planning, and resting for the upcoming birth of your next child.
There is arguably a better use of your time/energy right now. Relax and spend time with wife, remind her how much you love and support her. Take special care of the other kids, be the best husband & dad possible at this time.
Support your other kids and give them all the attention you can as the baby will take up 2 days minimum of total attention and from then on will have the spotlight instead of them.
Don't leave it to others (grandparents, other adults) to be the emotional support for your current children.
You have the rest of your life to debate glass on a gun. That $ could stay in your bank account for adulting expenses, diapers, wipes, sleep sacks, baby monitors, mattresses.

You only have 1-5 days or so to enjoy your time as a father to be again.
Best wishes to you, your wife, your kids, and your extended family and parents. You are blessed.
If you don't have a crib/movement baby monitor (that monitors breathing), get that first. Sell guns and glass to get it if you don't. Doesn't have to be Owlet as it's pricey. Just have something. No co-sleeping.
That mattress is awesome by the way. Not a gimmick. It's the AI of baby mattresses. NOBODY I know has returned or complained about it having bought it. The design is genius and the materials used are top notch. You can stick your face straight down into it and breathe right through it cover and all. Zero complaints about it other than price. My wife used to be a well-known baby gear tester/blogger.
Your time & $$$. Spend it the way you wish. Congrats on being a dad again!!!
