This question comes up a lot, the answer is not simple, but we can look at some general recommendation for how many plugins are needed and what most sites actually use in practice.
Remember, the more powerful your hosting, the better it will handle any heavy plugins you may need. I’d recommend the hosting options on our blog here: https://ideaspot.com.au/hosting/
My overal recommendation is curretnly Cloudways, you can get a free trial here: https://ideaspot.com.au/Cloudways (And use IDEASPOT coupon code to get a discount if you decide to continue after your trial)
