Looking to add a whole house filter system and a water softener combo, have a water report, need help understanding it

Here is a link to the latest report from my cities water supply. I unfortunately can't make sense of it and don't know if the levels are high or low on some things. I do know the water where I live a, suburb of Phoenix, AZ is very hard. It is very popular here to do a RO system or a softener. My house is 29 years old and it as far as I know has never had any type of water filtration or softener and I feel it is time. The problems I am faced with are in AZ my water that comes in the house is on the right side of my garage and the water heater is on the left and all the plumbing is run in the attic. To make the filter and the softener two different elements would be a strong feat to tackle. I see so many pics of jobs online of a filter and a water softener run together and the general consensus its soften after the filter especially when on municipal like I have. I thought I read that things like chlorine can be bad for a salt softener. I want to soften my hard water and filter the chemicals put in it from the city. I have my eye on a A.O. Smith filter and water softener ran together. From what I understand there may be instances where a softener is put before the filter, I plan to do mine after. Can anyone assure me that these two systems together will be sufficient for my house of two people one of which (me) that travels 10-15 days out of the month?

A.O. Smith Single-Stage 7-GPM GAC Whole House Water Filtration System combined with a A.O. Smith 35000-Grain Water Softener System (or larger haven't figured out my size needed yet).

Thank you in advance.
