Note that there are no "beacons" in the Wi-Fi sense, just packets going to a domain whose name begins with "beacon-handoff".

gvt2.com appears to be something Google-related; there's some code in Google's Chromium that uses it, and a VMware "Network Requirements for Android" pagealso mentions several Google domains, including gvt2.com.

So those TCP connections are probably some flavor of Android phoning home.

The akamaiedge.net traffic is probably talking to Akamai "edge cache" machinesthat store Web pages closer (in network-hop terms) to your machine - i.e., closer to the "edge" of the network - than the server is. I'll bet that the [a-z]-msedge.net is the same, with "Akamai" replaced by "Microsoft" (I'm guessing you're not running Microsoft's Edge browser on your phone, so that's probably not what the "edge" is).

MDNS is "Multicast DNS", which is used to do local host name lookup and service discovery. (Bonjour! :-)) The CACHE-FLUSH message is used when announcing services; as the Wikipedia page in question says, "The CACHE-FLUSH bit is used to instruct neighbor-nodes that the record should overwrite, rather than be appended onto, any existing cached entries...".

avast.com is an antivirus company, so the traffic is probably antivirus-related (checking for, or receiving, new definitions for new viruses?).

linkedin.com is LinkedIn.

The ICMPv6 packets with "Neighbor" in the name are part of the Neighbor Discovery Protocol, doing network configuration.

It presumably also told you where those packets came from or went to; just saying what the packets are only tells you that 1) something's using TCP, 2) something's using TLS (presumably over TCP), something's doing DNS lookups (which you sort of have to do if you want to access anything on the Internet), something's using ARP (which you have to do in order to use IPv4 on a network), something's using SSDP (I think printers tend do do that), and something's using mDNS (a number of systems, especially Apple systems, tend to do that; it and SSDP are both used to find other devices on the network, among other purposes).
