A solução listada aqui parecia funcionar, mas não funcionou. Depois de tentar, o firmware é listado no diretório acima:
-rw-r----- 1 root root 35127 Feb 5 01:26 BCM20702A1-13d3-3404.hcd
ATUALIZAÇÃO: Encontrei o firmware bcm20702a1 no Arch AUR aqui . Depois de remover o arquivo instalado acima, instalei o pacote do AUR (sem erros). Após a reinicialização, o problema ainda não foi resolvido.
O diretório acima agora inclui todos esses arquivos:

Observe que BCM20702A1-0b05-180a.hcd corresponde exatamente ao hardware listado em minha mensagem de erro, portanto, seria de se esperar que isso resolvesse o problema. Isso não aconteceu. No entanto, os logs parecem melhores, então talvez esse tenha sido um passo em direção a uma solução:

Atualização 2: após o último passo, mais uma etapa simples resolveu o problema:
systemctl start bluetooth.service
systemctl enable bluetooth.service
Vou escrever uma resposta com base nisso.
