Kurka, as I read this, I think I'm starting to be really old 
On the other hand, I am glad that at least I participated in this from the beginning.
Sufficient for me "speed of the Internet" stationary is 200Mb / s download and 40Mb / s upload (in real terms up to 50Mb / s upload). At home, 5 PCs, several phones, a tablet and an e-book are connected to the network (no smart TV, box and other such). I came to the conclusion that 100 Mb / s download was enough for 2-3 people, you could rarely feel any slowdowns. The link sometimes clogged up during cloud upload, file upload or social media upload due to the 20 Mb / s upload. Switching to 300 Mb / s download and 40 Mb / s upload solved the problem. Under the download degradation to 200 Mb / s with 40 Mb / s upload and a few golds in my pocket, I did not notice any negative effects of reducing the download transfer.

I started with 14.4K modems, real speed 1kB to 36.6K, real speed 2-3kB. Astronomical costs, at the level of x10 - x20 of a telephone subscription. US Robotics 56K, costs bearable, prepaid free tpsa sleepless nights, speed a little over 4kB, download times for mp3, first recorders and custom cd-audio compilations 
Then it's downhill: sdi 115.2K, adsl neostrada 1M then 2M (introduction of transfer limits, an offer to become a wifi service tester at a local operator), WiFi B / G, transfer at night for a few MB / s (wifi card in a stationary pc and panel antenna on the roof, initially for free as part of the tests), netia and a similar transfer as wifi (no limits, resignation from WiFi due to large and irregular ping for games, resignation from landline number, additional tps to maintain the line), WiFi on MikroTik, transfer over 10MB / s (small ping, no limits), additionally some tps incidental outside the place of residence and mobile internet such as Aero2 and LTE. I currently have FTTH. At the beginning it was 100 Mb / s down 20 Mb / s up, with no load on links 300 down / 20 up. I switched to 300 Mb / s down 40 Mb / s up, no load on connections 400 down / 50 up. Half a year ago I changed to 200 Mb / s download and 40 upload, with no load on 400/50 connections, at peak traffic it does not drop below 220/45. The only small disadvantage of optical fiber is the decrease in transfer by about half during the engine of storms or winds, due to the fiber swinging on electricity poles. It is a short-term illness, several times a year for several hours.
I believe the future is fast upload for the "private user" at home. More and more "private users" are active in the media on the Internet. I meet with the opinion that I would like to have 300 Mb / s upload at home as well as download and it could even be associated with transfer limitations as in LTE "mobile internet". Users want to "quickly put something on the Internet" and go a step further without planning the time for you to be tied to your desk with your pc. Paradoxically, the will to "healthy and active presence on the Internet" may force some people to participate directly in social life. Of course, there is a balance somewhere in the division of users, between those who will actively create "healthy media content" and those who will read, watch, listen and comment on it.

I also live in the countryside and I have something around 30Mbps (megabits, for the sake of clarity) on the cable. no optical fibers. You are also fine.
