Confused on best medical plan and HSA investing.

Hey everyone. Yall have been extremely helpful with opinions and analyses.

I started an exciting role with a new company and open enrollment is underway. I have my first kid due at the end of January (less than 2 months away). In your opinion, what is the best medical plan for my family (me, wife, and baby in January).

$1,000.00 PPO Plan (in-network)
- Deductible: Individual = $1,000.00 Family = $2,000.00
- Out of Pocket Max: Individual = $2,5000.00 Family = $5,000.00
- Biweekly premium: Family = $439.00

$3,000.00 HSA Plan (in-network)
- Deductible: Individual = $3,000.00 Family = $6,000.00
- Out of Pocket Max: Individual = $5,000.00 Family = $10,000.00
- Biweekly premium: Family = $226.00

$6,000.00 HSA Plan (in-network)
- Deductible: Individual = $6,000.00 Family = $12,000.00
- Out of Pocket Max: Individual = $6,000.00 Family = $12,000.00
- Biweekly premium: Family = $0.00

The company does not contribute to an HSA. Should I max my own contribution?
