As fellow being from the internet age, everyone needs to ensure their entire house is properly covered both with WLAN and wired internet access (and high speed network interconnects, so you can put a fat NAS and Media Server in some hidden compartment to stream movies and whatnot to various devices and accept print orders). There's also merit to rolling your own cloud, if bandwidth permits it, or renting a server and implementing it on there. Depending on your time and interest, setting up a VPN node might be neat as well so all your mobile phone traffic gets encrypted to avoid traffic shaping and nosy IT departments. Also, use all of those things as potential backup targets. Can't ever have enough backup locations.
That's some of what I was working on, back in the day when I still had a house. I'm living in an apartment now and 367% happier though, so YMMV.
Since you 'Murricans are still living in the Wild West, it might even be a good idea to slave some webcams to the whole setup so you can monitor your front door, porch etc - but make sure you're actually allowed to do that, permission-wise.

I'm not sure how often you sit out on the deck (noise, weather, visibility) but optimising it towards that use is always a nice idea.
HOA rules, space, personal inclinations and necessity permitting, install a foldable desk (basic solution: a piece of flat wood affixed to a wall with a hinge, plus an arrest mechanism), a noise and visibility cancelling wall towards the street and your neighbours (plants or opaque plastic), and a fire-proof grill emplacement.
Also weather proof storage solution for foldable chairs. Moody lights (maybe even one of those light strips things with changeable colours) and some relief from the sun and elements (from a plain old umbrella to something fancy like a grape-infested pergola) as well as some compartments with power supply for Bluetooth speakers, google home/amazon echo/etc slaveware, power outlets for chargers and such stuff might be a good idea as well. Don't forget to put some insulation in there so that the tech can't melt in the sun, drown in the rain or freeze during winter. This will play nicely with the next item: A Beamer in a weather proof enclosure and a proper reflective screen, or a used cheapo big TV, obviously with a media PC and/or various streaming dongles and/or consoles attached.
If you don't have a window that offers this functionality, add an access door to your kitchen within reach of the foldable desk so you can cook and prepare grill stuff and needn't drag it through your home to get it outside. Good for parties and convenient during day to day usage.
A cooler or at least drinking water tap for replenishment of body fluids is also always a good idea, although most porches have the latter already. Might be a good idea to encase it and frost-proof it so you don't need to futz around with it during the cold season.
Nothing like doodling your noodle in complete privacy under the open sky.
I mean, even if you don't want to, the mere possibility of actually being able to do that should give you some stress relief. Bonus points if your visibility screen allows you to still voluntarily make eye contact with neighbours or random people on the street. Assert your dominance.
