Expected Speeds of 5G Home Internet

For service in 85215 for home internet, originally the plans shows 85-300mbps and 300-1000mbps.  When I went to enroll, both plans had the same speeds of 85-300mbps.  Is the higher speed not offered yet in my area and by doing the $35 plan, am I simply paying for the privilege of the ability to purchase the sound bar and security system, and 1 extra year of price lock, or should I go to the $25 plan if I am only concerned with internet and speeds?  Right now speeds are around 180mbps
