I have an ESFP work colleague who I consider a friend, unfortunately she talks only about a few subjects (normally about celebrities or her most recent night out) and little else. I do enjoy her company if I don't seek much else conversation wise because I will get little else. I often want to go beyond first gear though and if I try to with her she will passively listen to me waffle on about a subject but certainly not follow up on anything I have said or any advice or insights I may have given. It's very much her way and really that's mostly all she does and from what I've seen in society what other ESFPs do. If she or another ESFP went mountain climbing or hiking for instance then I would accompany them and probably enjoy it but they don't. There's no surprise hobbies or extra layers for me to investigate, there is just that which is already presented. There just is not that much for me to "see, hear, taste, touch and smell" in the whole experience and that's what normally bores me in the end.
I have an ESFP co-worker and feel the same way towards her as well. She's a darling and cares for me a lot (often brings me food and checks up on me if she knows I feel sad) but most of what she talks about is superficial. I can't go into deep intellectual or philosophical discussions with her because she gives me that deer-in-the-headlights look or just nods to appease me and changes the conversation to something she's interested in. It's boring. (But they can still be a lot of fun in their own way!). I've also noticed that she talks wayyy too fast and needs the answers to her questions NOW lol.
My younger sister is an ESFP too and I can already see all of this developing.
